Tungsten Nickel Iron (W-Ni-Fe) Alloy is a kind of ternary alloy with tungsten as the matrix, adding appropriate amount of Ni and Fe. Tungsten content is about 90%- 98%, and the mass ratio of Ni to Fe is usually 7:3 or 1:1. Radio frequency (RF) plasma spheroidized W-Ni-Fe alloy powder has the characteristics of high sphericity, good fluidity, high purity and high bulk density, which can be used in medical devices, national defense and military industry, nuclear industry, and other fields.
TRM provides Spherical W-Ni-Fe Powder and the Heavy Tungsten Alloy (WNiFe and WNiCu) parts. Please contact us for more details.
