  • Tungsten has the highest melting point and lowest vapor pressure of all metals.
  • It also has excellent corrosion resistance and is not attacked easily by most mineral acids, so it is used a lot for glass-to-metal seals.
  • Tungsten has many other uses. It is used for filaments for electric lamps, television tubes, fly fishing, and x-ray targets. It is also used for metal evaporation.
  • Tungsten carbide is very important to the metal-working, mining, and petroleum industries
