Tungsten Heavy Alloys

Category:

Properties of tungsten heavy alloys:

  • High density (17-18.5g/cm3)
  • High melting point
  • Wear resistance
  • High tensile strength
  • Good elongation capacity
  • Low vapor pressure
  • Excellent thermal stability and
  • High radiation absorption capacity
  • Slightly Magnetic

Due to these advantages they are widely used in various fields including the sports, industry and medicine, etc. The most common high density tungsten alloys are Tungsten Nickel Iron Alloy (W-Ni-Fe Alloy) and Tungsten Nickel Copper Alloy (W-Ni-Cu Alloy).
