About Tungsten

Tungsten is white in pure form and has the highest melting point and lowest vapor pressure of all metals. It is among the heaviest of metals, with very high tensile strength and relatively high electrical conductivity. Small amounts of carbon and oxygen are often added to tungsten to enhance the material properties.

Tungsten Applications

  • Bearing shafts
  • Cathodes
  • Counter-balances
  • Electrode pins
  • Heating filaments
  • Micro piston
