Tungsten Powder Applications

  • Color and pigment. Used as a colorant and pigment in various ceramics and other compound materials.
  • Alloys. Can be used when producing certain forms of metal tungsten and tungsten alloys.
  • Data storage. Used to produce high-density memory storage devices.
  • Conductors. This material is frequently used for its electromagnetic properties to produce conductors and conducting nanofluids.
  • Semi-conductors. Tungsten powders can also be used to produce certain composite semiconducting materials.
  • Mechanochemical. The various mechanicochemical application can take advantage of the unique properties of tungsten. Specifically of use in solar energy conversion, smart windows, and related technologies.
  • Optics. Like many nanoparticles, tungsten offers unique optical properties as smaller scales, unseen at larger scales. This makes it useful in certain displays and imaging applications.
  • Alloys for the electronic package; Alloys for heat sinks; Anti-armor alloys; Circuit breakers; Contacts and electrode materials; Contacts in a protective atmosphere; Electrodes for gas sensors; Microelectronics films; Penetrators; Protective coatings; Sintering additives; Switchgear; Thermal management; Transformer tap changer; Vacuum contactors; Vacuum load switches…
  • Numerous tungsten alloys have numerous applications, including filaments of incandescent light bulbs, X-ray tubes (such as filaments and lenses), electrodes in TIG welding, superalloys, and radiation shielding. The hardness and high density of tungsten give military applications in penetrating bullets. Tungsten compounds are also often used as industrial catalysts.
  • The tungsten, or wolfram, is a chemical element with the symbol W and atomic number 74. The tungsten name derives from the former Swedish name for the tungsten ore of scheelite, tungsten, or “heavy stone”. Tungsten is a rare metal found naturally on Earth almost exclusively combined with other elements in chemical compounds instead of only. It was identified as a new element in 1781 and was first isolated as a metal in 1783. Its major minerals include wolframite and scheelite.
