Tungsten applications in aerospace and defense are among the most critical and fast-growing, underpinning modern kinetic, propulsion, and protection systems. Tungsten's exceptional density, high melting point, and strength make it irreplaceable in these demanding environments. This is a key driver of the tungsten market, with NATO members' increased defense spending and US Department of Defense programs creating strong, sticky demand [1].

In defense, tungsten is the primary material for kinetic energy penetrators (armor-piercing ammunition), where its density provides the mass needed to defeat heavy armor. It is also used in armor packages for military vehicles and in the throats of rocket nozzles, where its high-temperature resistance is vital. The U.S. Department of Defense has specifically flagged a 100% import reliance on tungsten concentrate and funded USD 435 million toward domestic conversion under Title III [1].

In the aerospace sector, beyond nozzles, tungsten alloys are used for gyroscope rotors, counterweights, and vibration-damping tooling. W-Re and W-Ta alloys are specified for high-temperature components in turbine engines and thrusters . The demand from this segment is expected to grow at a significant CAGR [1]. As hypersonic programs mature and defense budgets remain elevated, tungsten's role as a strategic material is only set to increase, solidifying its position as a cornerstone of national security.
