An extremely hard, high-melting-point metal used in cutting tools and armour.
A dense, high-melting-point metal (W, atomic number 74) with critical applications in cutting tools, drill bits, defense applications, and high-temperature components. China produces >80% of global tungsten, making it a strategic critical mineral.
Like antimony, supply concentration rather than geology is the story. Tungsten has no good substitute in machining, which makes even modest supply disruption disproportionately disruptive.
