Used as a filament in incandescent light bulbs due to its high melting point and durability. Commonly added to steel to create wear-resistant alloys for tools and machinery. Employed in aerospace components and high-temperature applications such as rocket nozzles and turbine blades. Utilized in electronics for wiring and contacts in integrated circuits. Found in radiation shielding and counterweights in aircraft and racing cars because of its high density. Also used in the production of hard metals like tungsten carbide for cutting tools and drill bits.
