Tungsten Nickel Iron Alloy (W-Ni-Fe)

Properties of tungsten nickel iron alloy (W-Ni-Fe Alloy):

  • 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 W-Ni-Fe Alloy and W-Ni-Cu Alloy.
Edgetech Industries LLC provides different kinds of tungsten heavy alloy products, we also manufacture them according to clients’ specifications.
