Tungsten Nickel Iron Alloy (W-Ni-Fe)
Properties of tungsten nickel iron alloy (WNiFe 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 Tungsten Nickel Iron Alloy (W-Ni-Fe Aalloy) and Tungsten Nickel Copper Alloy (W-Ni-Cu Alloy).
Edgetech Industries LLC provides different kinds of tungsten heavy alloy products, we can also manufacture them according to clients’ specifications.
