Metals whose supply is treated as a defence-procurement concern — rare earths, antimony, tungsten, titanium among them.
Metals and minerals deemed essential for military and defense applications, including rare earths (for precision-guided weapons), titanium (aircraft), tungsten (ammunition), and cobalt (jet engines). Defense metals often appear on critical minerals lists due to national security implications.
Defence demand is small in tonnage but policy-driven and price-insensitive, and it has recently pulled funding toward antimony and tungsten projects that would otherwise struggle to finance.
