Tungsten is widely used in high-temperature applications due to its exceptional heat resistance and high melting point. It is a key material in the production of filaments for incandescent light bulbs and fluorescent lamps. In the electronics industry, tungsten serves in semiconductor manufacturing and as interconnect material in integrated circuits. Its hardness and density make it ideal for manufacturing heavy alloy components used in aerospace, defense, and radiation shielding. Tungsten carbide, a compound of tungsten and carbon, is extensively used in cutting tools, drill bits, and wear-resistant parts for machining and mining equipment. It also finds use in the automotive and sports industries—such as in balance weights for tires and darts or golf club components—due to its high density and compact mass. In metallurgy, tungsten is added to steels and superalloys to improve strength, toughness, and resistance to high-temperature deformation.
