What is tungsten used for?

Tungsten extracted from scheelite has a high melting point, high density, high strength, as well as good electrical and thermal conductivity, making it an important strategic metal.

    Manufacture of hard alloys: Tungsten carbide is a key raw material in the manufacture of hard alloys. Hard alloys, known for their high hardness and wear resistance, are widely used in crafting cutting tools, drill bits, planer blades, grinding tools, and more.
  • Manufacture of high-temperature alloys: Tungstens high melting point makes it ideal for crafting components for aerospace engines, nuclear reactors, and other high-temperature applications.
  • Electronics industry: Tungsten is also used in the manufacturing of filaments, electrodes, electronic devices, vacuum tubes, light-emitting diodes (LEDs), and more.
  • Radiation shielding materials: Tungsten has good absorption capabilities for X-rays and gamma rays, making it useful as a radiation shielding material in medical and nuclear industries.
  • Chemical catalysts: Tungsten compounds are also used as components in chemical catalysts for organic synthesis and other fields.
