Tungsten: uses

The following uses for tungsten are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additional referenced uses.

  • useful for glass-to-metal seals since the thermal expansion is about the same as borosilicate glass
  • tungsten and its alloys are used extensively for filaments for electric lamps, electron and television tubes, and for metal evaporation work
  • electrical contact points for car distributors
  • X-ray targets
  • windings and heating elements for electrical furnaces
  • missile and high-temperature applications
  • high-speed tool steels and many other alloys contain tungsten
  • the carbide is important to the metal-working, mining, and petroleum industries
  • calcium and magnesium tungstates are widely used in fluorescent lighting
  • tungsten salts are used in the chemical and tanning industries
  • tungsten disulphide is a dry, high-temperature lubricant, stable to 500°C
  • tungsten bronzes and other tungsten compounds are used in paints
  • TV tubes (electron tubes)
  • X-ray targets
