Tungsten

The hardest and most heat-resistant metal, suffering from one of the most extreme supply concentrations in the world.

Overview

Tungsten is an incredibly dense, hard metal with the highest melting point of all metals (3,422 °C). When combined with carbon to form tungsten carbide, it provides irreplaceable wear resistance for cutting, drilling, and machining tools across construction, energy, and aerospace. The global supply chain is dominated by China, which controls over 80% of mine production and over half of global reserves, making tungsten a high-priority critical mineral for Western governments.

Highly recyclable from scrap carbides, tool steels, and high-density alloys. The US relies heavily on recycling due to zero domestic mining.

Constraints & Risks

China ≈83%. Extreme geographic concentration.

Refining HHI

China dominates APT and oxide conversion.

Chokepoints

The entire supply chain—from mine to APT to powder—is heavily centered in China.Non-Chinese concentrate production is only ~20% of the global total.

Environmental Considerations

  • Historic tungsten mine tailings often contain pyrite and arsenic-bearing minerals, requiring careful management to prevent acid mine drainage.
  • Tungsten itself is not considered highly toxic, but co-occurring metals in the ore body pose localized environmental risks.
  • Reprocessing historic tailings offers a potential dual benefit of environmental remediation and secondary tungsten recovery.
1

Extreme Geographic Concentration

China produces roughly 83% of global mine output and controls ~52% of reserves. Production outside of China is highly fragmented.

Impact

High vulnerability to Chinese export quotas, tariffs, or geopolitical disruptions. Western project pipelines are slow to develop.

Mitigation

Development of new projects in South Korea, Canada, Australia, and Africa; scaling up of scrap recycling.

2

Lack of Viable Substitutes

Tungsten's extreme hardness and heat resistance cannot be easily replicated. Substitutes (like molybdenum or titanium carbides) often result in higher costs or lower performance.

Impact

Demand is highly inelastic; critical industries (defense, aerospace, machining) must secure tungsten regardless of price.

Mitigation

Intensive recycling programs for end-of-life tooling.

3

US Domestic Dependency

The US has had no commercial tungsten mining since 2015, relying entirely on imports and scrap recycling to feed its downstream conversion facilities.

Impact

Exposure to supply shocks for critical defense and industrial applications.

Mitigation

USGS Earth MRI program mapping domestic resources; Section 301 tariffs applied to Chinese imports to spur domestic/allied production.

Substitution & Alternatives

What Could Replace Tungsten?

Titanium/Molybdenum Carbides

Replacing in: Cutting tools, hardmetals

Limited

Often results in lower wear resistance or shorter tool life compared to tungsten carbide.

Depleted Uranium

Replacing in: Kinetic-energy penetrators, shielding

Partial

Effective density, but carries severe environmental, health, and regulatory liabilities compared to tungsten alloys.

FAQ

Frequently Asked Questions

Tungsten is the backbone of industrial machining. About 60% of it is used to make cemented tungsten carbides—the ultra-hard material used for drill bits, saw blades, and cutting tools that shape other metals, rocks, and materials.

It combines irreplaceable performance in defense, energy, and manufacturing with an extreme supply concentration. China controls over 80% of production and half of all reserves, creating a massive geopolitical chokepoint for Western industries.

Not easily. While some applications can use ceramics, molybdenum, or titanium carbides, these alternatives usually offer inferior performance or higher costs in high-stress, high-heat environments.

No. The US has not had active commercial tungsten mining since 2015. It relies entirely on imports and the recycling of scrap to feed its domestic processing facilities.
