Spherical Tungsten-Nickel-Iron Alloy Powder Application

Tungsten-nickel-iron alloy is a kind of tungsten matrix, adding the appropriate amount of nickel, iron composition of the ternary alloy, tungsten content is about 90%~98%, and the mass ratio of nickel and iron is usually 7:3 or 1:1. Radiofrequency plasma spheroidized tungsten-nickel-iron alloy powder has the characteristics of high sphericity, good fluidity, high purity, and large loose density, etc. It can be used in medical instruments, national defense, the nuclear industry, and other fields.
