In Europe’s strategic mineral landscape, tungsten and specialty metals such as molybdenum, titanium, and high-performance alloys occupy a critical niche at the intersection of defence, aerospace, and industrial resilience. Unlike battery metals, which are primarily linked to electrification, these materials underpin armour systems, jet engines, guidance components, and other defence-critical technologies that require performance precision and have few substitutes.
Tungsten stands out for its extremely high melting point, density, and mechanical durability, making it essential for kinetic penetrators, armour-piercing ammunition, and high-temperature industrial applications. Europe has historically relied on imported tungsten, with most processing concentrated in Asia. Domestic sources are limited, with examples like Almonty Industries’ Los Santos Mine in western Spain, which extracts scheelite (CaWO₄). Despite price volatility over the years, Los Santos has remained operational under Almonty’s stewardship, representing one of Europe’s few indigenous tungsten sources.
Europe’s defence procurement policies increasingly prioritize resilient, near-shore tungsten supply, reducing exposure to global market shocks. Tungsten’s density (~19.3 g/cm³) and melting point (over 3,400°C) make substitutes technologically impractical in many defence and aerospace applications, including penetrator cores and aerospace counterweights.
Specialty Metals Beyond Tungsten
Other strategic metals reinforce Europe’s defence and aerospace capabilities. Titanium alloys, valued for their high strength-to-weight ratio and corrosion resistance, are used in aircraft frames and naval vessels, while molybdenum alloys support high-temperature turbine components. These materials share a common theme: integration into mission-critical systems where failure is not an option, driving procurement policies toward geopolitically stable and technologically robust supply chains.
Europe addresses these needs through a combination of domestic mining, alloy production, and industrial recycling. Recycling plays a growing role, especially for refractory metals like tungsten, where industrial scrap, carbide tools, and machining by-products can be reprocessed into high-value alloys. This reduces reliance on primary mining and helps stabilize supply, a key concern for defence planning.
The Critical Raw Materials Act (CRMA) incorporates defence-critical metals within Europe’s broader strategic mineral priorities. Projects contributing to aerospace or defence supply chains may qualify for accelerated permitting and coordinated financing, reinforcing alignment between industrial policy and national security objectives.
Market Realities and Challenges
The tungsten and specialty metals market is inherently complex:
-
Price volatility is common due to concentrated global supply and industrial demand cycles.
-
Processing capacity is capital-intensive, requiring specialized furnaces, alloying plants, and strict quality control systems.
-
Financing often depends on long-term offtake agreements with defence contractors or government stockpiles.
While demand for defence metals is less cyclical than consumer markets, revenue stability is closely tied to government procurement budgets and geopolitical tensions. Strategic stockpiling can mitigate supply shocks but involves significant capital allocation and opportunity costs.
Strategic Implications for Europe
Europe’s emphasis on tungsten and specialty metals underscores that raw material strategy extends beyond EV batteries and renewable energy. Defence applications require a diversified approach blending:
-
Domestic mining,
-
Industrial recycling,
-
Specialized processing, and
-
Targeted policy support.
As geopolitical competition intensifies, tungsten and other specialty metals will remain central to Europe’s industrial policy and defence planning. The integration of these materials into CRMA strategic project frameworks and allied defence programs represents a vital step toward supply chain resilience, even amid market, technological, and regulatory complexities.
