1. INTRODUCTION

Metallurgy, one of humanity's oldest technologies, is experiencing a renaissance driven by computational power, environmental necessity, and materials science breakthroughs. The traditional trial-and-error approach that dominated materials development for millennia is giving way to precision-guided design enabled by artificial intelligence, quantum computing, and advanced characterization techniques.

This transformation is occurring across multiple fronts simultaneously. Researchers are discovering materials with atomic-level precision using machine learning algorithms that can predict properties before synthesis. Industrial steel production, responsible for nearly 8% of global carbon emissions, is being revolutionized through hydrogen-based processes. Exotic quantum materials are transitioning from physics laboratories to commercial quantum computers. And advanced manufacturing techniques are enabling the creation of materials with properties impossible through conventional metallurgy.

The confluence of these developments creates unprecedented opportunities—and challenges. This white paper provides a comprehensive analysis of the seven most significant metallurgical breakthroughs expected between 2025 and 2030, examining their technical foundations, commercial viability, implementation timelines, and potential impact on industries ranging from aerospace to electronics to sustainable energy.

Methodology

This analysis is based on extensive research conducted in October 2025, including:

• Review of 60+ peer-reviewed publications and industry reports from 2024-2025
• Analysis of major research programs from MIT, Caltech, Max Planck Institute, and other leading institutions

2. HIGH-ENTROPY ALLOYS: THE MATERIALS REVOLUTION

2.1 Technical Overview

High-entropy alloys (HEAs) represent a fundamental paradigm shift in alloy design. Traditional alloys are built around a single dominant base metal (such as iron in steel or aluminum in aircraft alloys) with minor alloying elements added to modify properties. HEAs invert this approach by incorporating multiple principal elements—typically five or more—in roughly equiatomic proportions with no single dominant component.

This revolutionary compositional strategy, first conceptualized by researchers Yeh et al. in 2004, broadens the scope of alloy design exponentially. The high configurational entropy stabilizes single-phase solid solutions that would be thermodynamically impossible in conventional alloys, creating materials with exceptional mechanical properties including:

• Ultrahigh strength exceeding 1.25 GPa
• Superior thermal stability at extreme temperatures
• Exceptional corrosion and wear resistance
• Remarkable radiation tolerance for nuclear applications

A 2025 review in Current Opinion in Solid State and Materials Science describes how the field has evolved from high-entropy alloys (HEAs) to the broader concept of "alloys with high entropy" (AHEs), encompassing high-entropy steels, superalloys, and intermetallics. This evolution introduces additional design parameters including stacking fault energy (SFE), lattice misfit, and anti-phase boundary energy (APBE) that significantly influence material performance.

2.2 Key Applications and Breakthroughs (2025-2030)

Ultra-Hard HEAs for Manufacturing

Recent work published in the Journal of Alloys and Compounds demonstrates the application of machine learning with Gradient Boosting-based Statistical Feature Selection (GBFS) to design ultra-hard high-entropy alloys. This methodology identifies key compositional and structural features from high-dimensional data, enabling predictive models that match experimental results with remarkable accuracy.

These ultra-hard HEAs show tremendous promise for:

• Cutting tools and industrial machining applications
• Wear-resistant coatings for extreme environments
• Aerospace structural components requiring exceptional hardness

Electrocatalytic Applications

A comprehensive review in Materials & Design (2025) explores HEAs as transformative electrocatalysts. The compositional complexity of HEAs—incorporating five or more principal elements into single- or multiphase solid solutions—enables exceptional tunability of electronic structures, adsorption energies, and catalytic behavior.

HEAs are demonstrating superior performance across key electrocatalytic reactions:

• Hydrogen Evolution Reaction (HER) for water splitting
• Oxygen Evolution Reaction (OER) and Oxygen Reduction Reaction (ORR)
• Carbon Dioxide Reduction (CO₂RR) and Nitrogen Reduction (NRR)
• Fuel cell applications (methanol and ethanol oxidation)

Research published in Communications Materials (2025) highlights how surface optimization strategies—including composition regulation, phase engineering, dimensional control, heterogeneity design, and defect engineering—are crucial for maximizing nanostructured HEA performance in sustainable energy technologies.

Electromagnetic Shielding and Defense

Advanced Engineering Materials published groundbreaking research in May 2025 demonstrating HEAs' potential for next-generation electromagnetic interference (EMI) shielding. HEAs are being developed in various forms—coatings, composites, and metasurfaces—with exceptional electromagnetic wave absorption properties.

Key advantages for defense and commercial applications include:

• Superior corrosion resistance for long-term durability
• Thermal stability for high-temperature operations
• Mechanical strength combined with electromagnetic properties
• Potential for multispectral stealth materials spanning infrared, microwave, and optical applications

Nuclear Reactor Materials

Research published in the Journal of Materials Science (December 2024) explores HEAs for nuclear applications, particularly for Generation IV reactors operating under harsh conditions of high temperature and intense irradiation. Refractory HEAs (RHEAs) based on the ZrNbVTiAl system show exceptional promise.

Indian research teams at Bhabha Atomic Research Centre (BARC) have achieved significant progress:

• Strengths up to 1.25 GPa in equiatomic and non-equiatomic compositions
• Excellent fabricability through dynamic recrystallization at high temperatures
• Superior irradiation resistance due to BCC-based structures
• Development of TaVTiWCr system alloys for fusion reactor applications

Remarkably, preliminary studies indicate that irradiation can push multiphase HEA structures toward single phase—potentially revolutionizing how these materials are classified and applied in the nuclear sector.

2.3 Commercial Outlook and Challenges

Materials Horizons published a comprehensive review in 2025 identifying HEAs as potential "4th Industrial Revolution materials" due to their exceptional mechanical strength, thermal stability, corrosion resistance, and tailored functional properties. Examples include NbMoTaW for jet engine applications and TiZrNbTaMo for medical implants, showcasing versatility under extreme conditions.

Key challenges for 2025-2030:

• Scaling production from laboratory to industrial quantities
• Reducing raw material costs (many HEAs contain expensive elements)
• Developing consistent processing techniques across compositions
• Establishing supply chains for multi-element alloy production
• Creating industry standards and certification processes

Despite these challenges, the Journal of Bio- and Tribo-Corrosion notes that advances in fabrication techniques—from traditional casting and powder metallurgy to state-of-the-art additive manufacturing—are expanding HEA applications in aerospace, energy, and automotive sectors.

3. AI-DRIVEN MATERIALS DISCOVERY: SPEED REVOLUTION

3.1 The Transformation of Materials Science

A comprehensive review published in ACS Nano (October 2025) declares that "the era has arrived in which artificial intelligence (AI) autonomously imagines and predicts the structures and properties of new materials." AI now functions as a researcher's "second brain," actively participating in every stage of research from idea generation to experimental validation.

This transformation is occurring across three critical stages:

Discovery Stage:

AI designs new structures, predicts properties, and rapidly identifies the most promising materials among vast candidate pools. Machine learning models trained on extensive databases can screen millions of compositions in hours rather than years.

Development Stage:

AI analyzes experimental data and autonomously adjusts experimental processes through self-driving lab systems, significantly shortening research timelines. These systems can run 24/7, continuously learning and optimizing.

Optimization Stage:

AI employs reinforcement learning and Bayesian optimization to fine-tune designs and process conditions for maximum performance, efficiently finding superior results with minimal experimentation.

3.2 Self-Driving Laboratories and Autonomous Discovery

MIT researchers unveiled the Copilot for Real-world Experimental Scientists (CRESt) platform in September 2025, representing a breakthrough in autonomous materials discovery. Unlike conventional machine learning models that consider only specific types of data, CRESt incorporates diverse information sources:

• Insights from scientific literature
• Chemical compositions and synthesis parameters
• Microstructural images and characterization data
• Real-time experimental feedback
• Human expertise and intuition

The platform employs robotic equipment for high-throughput materials testing, with results fed back into large multimodal models to continuously optimize materials recipes. In a remarkable demonstration, CRESt explored over 900 chemistries in just three months, discovering a catalyst material for direct formate fuel cells that achieved a 9.3-fold improvement in power density per dollar compared to pure palladium.

The system's active learning approach is particularly powerful:

• Creates knowledge embeddings from literature and databases before experiments
• Performs principal component analysis to identify reduced search spaces
• Uses Bayesian optimization to design new experiments
• Incorporates multimodal experimental data and human feedback into large language models
• Continuously redefines search spaces for maximum efficiency

3.3 Major AI Platforms and Initiatives

Google DeepMind's GNoME

In late 2023, Google DeepMind announced its Graph Networks for Materials Exploration (GNoME) system, which used deep learning to discover 2.2 million new crystalline materials. While critics raised concerns about the practicality of some predictions, a Nature article from September 2025 notes that behind the hype, there is genuine progress.

The GNoME database includes:

• 52,000 simulations of layered compounds similar to graphene
• 528 potential lithium-ion conductors for improved batteries
• Diverse compounds spanning the periodic table

A-Lab: Autonomous Synthesis

In a companion effort involving DeepMind researchers, the robotic 'A-Lab' demonstrates autonomous materials synthesis. The system:

• Learns from tens of thousands of published synthesis papers
• Devises recipes for target compounds predicted by density functional theory (DFT)
• Deploys physical robots to synthesize compounds
• Analyzes products to verify they match targets
• Iteratively tweaks recipes based on results

Microsoft MatterGen

Microsoft unveiled MatterGen shortly after GNoME's announcement. Like GNoME, it's a machine-learning model trained to generate stable crystal structures, though with different architectural approaches and optimization strategies.

3.4 Specialized Applications

Steel Alloy Design

Scientific Reports published research in 2021 (recently validated in 2025 implementations) on a machine learning-based platform for thermo-mechanically controlled processed (TMCP) steel alloys. The system collected 16 descriptors (compositional and processing information) for 5,473 steel alloys, achieving:

• R² > 0.6 and MSE < 0.01 for yield strength and tensile strength predictions
• Both forward predictions (properties from composition) and inverse design (composition from desired properties)
• Multi-objective optimization using genetic algorithms (NSGA-II)

Magnesium Alloy Development

A comprehensive review in Frontiers in Materials (July 2025) examines computational methods and AI-based modeling for magnesium alloys. The field employs:

• Machine learning for predicting mechanical behavior (yield strength, tensile strength, fatigue life)
• Deep learning for microstructure characterization (grain size, dislocation density, texture)
• Active learning frameworks with Pareto optimization for multi-objective design
• Bayesian optimization for accelerated composition screening

One notable success: researchers designed Al-Mg-Zn alloys achieving ultimate tensile strength of 602 MPa with 15.1% elongation through iterative learning.

3.5 Government and Defense Initiatives

MIT's Materials Day 2025 conference featured Matthew Draper, technical director of metallurgy and manufacturing for the U.S. Department of Defense's Innovation Capability and Modernization (ICAM) Office. Draper announced that the DoD is building a network of programs to accelerate materials discovery:

"By mid-2027, researchers using this network will be able to go from walking in with a concept to having metal samples and certification data in less than three months."

This represents a reduction from the typical 10-20 year timeline for traditional materials development—a potential 40-80x acceleration.

3.6 Challenges and Limitations

Despite dramatic progress, significant challenges remain:

• Data Quality and Availability: Many materials lack comprehensive property databases, limiting training data
• Validation Gap: AI can predict millions of materials, but experimental validation remains slow and expensive
• Synthesizability: Thermodynamically stable materials predicted by AI may be impossible to synthesize in practice
• Interpretability: Understanding why AI recommends specific compositions remains challenging
• Integration Barriers: Bridging AI predictions with traditional metallurgical manufacturing requires new infrastructure

The World Economic Forum (June 2025) emphasizes that leveraging both domain expertise and data-driven insights through AI-enabled platforms will be essential for transforming materials science.

4. GREEN STEEL AND HYDROGEN METALLURGY: DECARBONIZATION IMPERATIVE

4.1 The Carbon Challenge

Steel production is one of the most carbon-intensive industrial processes, accounting for approximately 7-8% of global CO₂ emissions. Traditional blast furnace-basic oxygen furnace (BF-BOF) steelmaking produces about two tons of carbon dioxide per ton of steel. With global steel production exceeding 1.95 billion tons annually, the industry's environmental impact is staggering.

MIT Technology Review designated "green steel" as one of its 10 Breakthrough Technologies for 2025, highlighting the urgency and feasibility of hydrogen-based steel production. The transformation from carbon-based to hydrogen-based metallurgy represents the most significant change in iron and steel production since the Industrial Revolution.

4.2 Hydrogen Direct Reduction Technology

Technical Process

Hydrogen-based direct reduction replaces carbon (coke) with hydrogen as the reducing agent for converting iron ore (iron oxide) into metallic iron. The fundamental chemical reactions are:

Traditional (Carbon-based):

Fe₂O₃ + 3C → 2Fe + 3CO₂

Hydrogen-based:

Fe₂O₃ + 3H₂ → 2Fe + 3H₂O

The critical difference: the byproduct is water vapor rather than carbon dioxide. When the hydrogen is produced through water electrolysis using renewable electricity ("green hydrogen"), the entire steelmaking process can achieve near-zero emissions.

Research published in npj Materials Degradation (October 2023) examined a crucial concern: hydrogen embrittlement. The study quantified hydrogen content in iron produced via two hydrogen-based processes (direct reduction and plasma smelting reduction), finding no threat of embrittlement from green steel production processes.

4.3 Commercial Implementations

Stegra (H2 Green Steel) - Sweden

Stegra (formerly H2 Green Steel), a Swedish startup founded in 2020, represents the most advanced commercial-scale green steel project globally. The company has raised nearly $7 billion in financing—one of the largest green technology investments in European history.

Key project specifications:

• Location: Boden, northern Sweden
• Capacity: 2.5 million tons per year initially
• Start date: 2026
• Technology: 100% hydrogen direct reduced iron (DRI), supplied by MIDREX H2™ Plant from Midrex and Paul Wurth
• DRI production: 2.1 million tons per year of hot DRI (HDRI) and hot briquetted iron (HBI)
• Hydrogen source: Water electrolysis using renewable electricity (wind and hydropower from Swedish grid)
• Emissions: Near-zero CO₂

Customer commitments already secured include:

• Volvo (planning to purchase zero-emissions steel by 2026)
• Porsche
• Mercedes-Benz
• Scania
• Purmo Group

HYBRIT - Sweden

HYBRIT (Hydrogen Breakthrough Ironmaking Technology) is a joint venture of SSAB, LKAB, and Vattenfall. Having successfully demonstrated the process at a pilot plant in Luleå, the next phase involves:

• Demonstration plant being built by LKAB at Gällivare
• Green pellets from LKAB
• Green hydrogen from Swedish grid renewable electricity
• SSAB will use green DRI at Oxelösund works and eventually Luleå works
• Conversion to electric arc furnace (EAF) steelmaking
• Commercial-scale production targeted for 2026

HBIS Group - China

China's HBIS Group successfully delivered first green DRI products from the world's first 1.2 million ton hydrogen steelmaking pilot plant. Key innovations:

• Uses coke oven gas (a byproduct of steel production) as hydrogen source initially
• Zero-retrofit vertical furnace direct reduction technology
• Designed to accommodate future green hydrogen integration
• BMW Shenyang Plant will use HBIS green steel starting 2026 for full automobile production

Boston Metal - United States

Boston Metal, an MIT spinoff, has developed Molten Oxide Electrolysis (MOE) technology that represents an alternative approach to green steel:

• Passes electric current through iron oxide and other oxides
• Eliminates blast furnaces entirely
• Does not require hydrogen
• Secured $120 million in funding from ArcelorMittal and Microsoft
• Demo plant planned for 2024, commercial plant by 2026

4.4 Breakthrough Furnace Technologies

The World Economic Forum's First Movers Coalition near-zero steel challenge (April 2024) identified promising enabling technologies. Finnish company Coolbrook developed RotoDynamic Technology, ranked as the highest-potential furnace innovation:

• Generates high-temperature process heat up to 1,700°C through electrification
• Eliminates fossil fuel combustion completely
• Potential to remove 600 megatonnes of iron and steel-related CO₂ emissions annually
• Can replace existing furnaces without complete facility rebuilds

4.5 Hydrogen Production Challenge

The critical bottleneck for hydrogen metallurgy is not the steelmaking technology itself, but rather hydrogen production at scale. According to the International Energy Agency (IEA), green hydrogen will not be available at industrial scale until after 2030—currently less than 0.1% of global dedicated hydrogen production comes from water electrolysis.

Hydrogen Classification:

• Green Hydrogen: Produced via electrolysis using renewable electricity (wind, solar, hydro)
• Blue Hydrogen: Produced from natural gas with carbon capture and storage (CCS)
• Pink Hydrogen: Produced via nuclear-powered electrolysis
• Gray Hydrogen: Produced from natural gas without CCS (current dominant method)

Under IEA's Sustainable Development Scenario, global hydrogen demand will increase to 287 million tons per year by 2050—a 400% increase from 2020 levels. This demand spans multiple industries beyond steel:

• Transportation (aviation, shipping, heavy trucking)
• Ammonia production for fertilizers
• Chemical manufacturing
• Energy storage and power generation

A key question remains unanswered: priority allocation. When green hydrogen becomes available, which industries will receive preferential access? This policy decision will significantly impact the pace of steel industry decarbonization.

4.6 Economic Considerations

ING Bank's analysis (July 2023) examined the economics of green steel adoption:

Green Premium Impact:

• Automotive: Steel represents minor share of total vehicle cost, making green premium manageable
• Construction: Less visible to consumers, adoption may be slower
• Consumer electronics: Durable coatings becoming a differentiator

Volkswagen exemplifies automotive commitment: partnering with Salzgitter AG to source green steel for the Trinity1 e-model beginning in 2025, with full production starting 2026.

Cost reduction targets are aggressive. Hydrogen production costs must fall dramatically to achieve commercial viability at scale. Government support through:

• Direct subsidies for green hydrogen production
• Carbon pricing mechanisms
• Research and development funding
• Infrastructure investment (pipelines, storage, distribution)

will be essential for the transition.

4.7 Geographic and Policy Landscape

E&E News (February 2024) reported stark differences between U.S. and European approaches:

European Leadership:

• Swedish firms SSAB and H2 Green Steel demonstrating zero-emissions steel
• Multiple contract commitments with automakers
• Strong policy support and carbon pricing
• Abundant renewable electricity

United States Challenges:

• "Notable lack of government support or incentives" for capacity transition
• Limited green iron production scaling
• Hydrogen infrastructure gaps (pipelines, storage, distribution)
• BUT: All necessary conditions exist—could catch up rapidly with right policy

Columbia University's Chris Bataille noted: "The U.S. is behind in policy and investment in green steel, but it could catch up really fast with the right policy. It's got all the right ingredients."

The U.S. Department of Energy is negotiating $7 billion in grants for hydrogen demonstration clusters, which could accelerate American progress significantly.

4.8 Timeline and Projections

RMI (formerly Rocky Mountain Institute) estimates that approximately 50 hydrogen-fueled steel plants globally are needed by 2030 to meet decarbonization targets. Chris Bataille projects that more than 25% of steel production will achieve near-zero emissions by 2050.

Key Milestones:

• 2025-2026: First industrial-scale plants begin operation (Stegra, HYBRIT)
• 2026-2028: Major automotive contracts fulfilled, proving commercial viability
• 2027-2030: 50+ plants operational globally, blue hydrogen as interim solution
• 2030-2035: Green hydrogen scales, costs decline, widespread adoption begins
• 2040-2050: 25%+ of global steel production near-zero emissions

The 2026 startup of Stegra's facility represents a watershed moment—the first proof that green steel can be produced at true industrial scale with viable economics.

5. QUANTUM AND TOPOLOGICAL MATERIALS: COMPUTING REVOLUTION

5.1 Fundamental Concepts

Topology, a mathematical concept, has revolutionized materials science over the past three decades. As reviewed in Chemical Reviews, there is a direct connection between real space (atoms, electrons, bonds, orbitals) and reciprocal space (bands, Fermi surfaces) via symmetry and topology, enabling classification of topological materials within a single-particle picture.

Materials are now classified as:

• Trivial insulators, semimetals, and metals (conventional materials)
• Topological insulators (insulating in bulk, conducting on surface)
• Dirac and Weyl nodal-line semimetals (exotic electronic dispersion)
• Topological metals (metallic with topological surface states)

Remarkably, over 20% of all inorganic compounds are topological. The key ingredients for topology are:

• Certain symmetries
• Inert pair effect leading to band inversion
• Spin-orbit coupling

5.2 Topological Quantum Computing Breakthrough

In January 2025, Microsoft's Station Q team, led by UC Santa Barbara physicist Chetan Nayak, unveiled the first eight-qubit topological quantum processor—a watershed moment for quantum computing. This chip, named Majorana 1, proves the feasibility of topological quantum computing after decades of theoretical development.

Why Topological Qubits Matter:

Traditional qubits (superconducting, ion-trapped, photonic) are fragile and prone to errors from environmental disturbances. Topological qubits offer fundamentally different physics:

• Based on anyons (quasiparticles emerging from correlated states at material surfaces)
• Information stored non-locally (distributed across physical system, not individual particles)
• Hardware-level error protection (inherent stability, not requiring extensive error correction)
• Computation through 'braiding' (physically moving Majorana zero modes around each other)

The Microsoft Achievement:

The researchers realized Majorana zero modes (MZMs) through precise placement of indium arsenide semiconductor nanowires very close to aluminum superconductors. While eight qubits is modest compared to IBM or Google's systems (with hundreds of qubits), the significance lies in proving the topological approach works.

New Characterization Techniques

University College Cork researchers, published in Science (May 2025), developed breakthrough visualization techniques using scanning tunneling microscopy (STM) in "Andreev" mode—found only in three laboratories worldwide (Cork, Oxford, Cornell). This method:

• Uses superconducting probes instead of metallic probes
• Excludes normal surface electrons from measurements
• Isolates Majorana fermions for direct observation
• Enables definitive determination of topological superconductor suitability

They confirmed that Uranium ditelluride (UTe₂) is an intrinsic topological superconductor, though not exactly the type sought. Critically, this technique allows scientists to rapidly screen candidate materials—previously an impossibly slow process.

5.3 Kagome Lattice Materials

Kagome lattice materials—two-dimensional structures of corner-sharing triangles—have emerged as a fascinating playground for topological physics. Research published in npj Quantum Materials (July 2025) and Accounts of Materials Research explores their unique properties.

Key Features:

• Geometric frustration: Triangular arrangement prevents simple magnetic ordering
• Dirac points: Linear band crossings creating massless fermions
• Van Hove singularities: High density of states enabling strong correlations
• Flat bands: Zero dispersion creating strongly correlated electrons

Important Materials:

• Fe₃Sn₂: Massive Dirac fermions near Fermi level
• Co₃Sn₂S₂: Large intrinsic anomalous Hall effect, magnetic Weyl fermions
• YMn₆Sn₆: Frustrated magnetism with topological bands
• FeSn: Flat band physics

These materials exhibit giant anomalous Hall effects—Berry curvature in momentum space significantly enhances electronic response. Some host topologically protected skyrmion lattices or noncoplanar spin textures, yielding topological Hall effects from real-space Berry phase.

5.4 Commercial and Defense Applications

Spintronics

Topological materials with strong spin-orbit coupling enable next-generation spintronic devices where electron spin (not just charge) carries information. Advantages:

• Lower power consumption
• Faster switching speeds
• Non-volatile memory

7. METALLIC GLASSES: COMMERCIAL BREAKTHROUGH

7.1 What Are Metallic Glasses?

Metallic glasses, also called bulk metallic glasses (BMGs) or amorphous metals, are metals with disordered atomic structure—no crystalline lattice. First created at Caltech by Pol Duwez in 1957, they're produced by cooling alloys rapidly enough to prevent crystallization, "locking in" the random atomic arrangement of the liquid state.

Extraordinary Properties:

• Strength: Vitreloy has tensile strength nearly double that of high-grade titanium

• Energy infrastructure: Amorphous metal transformer cores improving efficiency
• Automotive: Clean energy technologies adoption
• Defense and aerospace: U.S. requirements for advanced materials

The U.S. metallic glasses market alone was valued at $530 million in 2024, expected to grow at 6% CAGR through 2034.

7.3 NASA-Derived Robotics Applications

NASA Spinoff featured Amorphology Inc., a Pasadena startup commercializing JPL/Caltech metallic glass patents. Founded by JPL's foremost pioneer of metallic glasses and metal 3D printing, the company is revolutionizing robot gears.

The Problem:

Collaborative robots (cobots) are becoming essential for manufacturing, but their cost—largely driven by expensive precision gears—limits widespread adoption. Traditional flexsplines (critical components of strain wave gears) are:

• Cut, ground, and drilled from steel billets
• Time-consuming to manufacture
• Expensive (major cost driver)
• Require liquid lubricants

The Solution:

Amorphology injection molds flexsplines from metallic glass:

• 70% faster production compared to Metal Injection Molding (MIM)
• Significantly lower cost (single-step process)
• No lubrication needed (hard, smooth ceramic oxide surface)
• Long lifetime (superior wear properties)
• Complex geometries (thermoplastic forming)

Additional customer applications include coating consumer electronics parts with metallic glass for enhanced durability. Food manufacturing industries show interest in lubrication-free gears where lubricants could contaminate products.

7.4 Commercial Alloy Families

Glassimetal Technology has developed several commercially viable BMG families:
