Copper Tungsten — Chinatungsten Online

201836 · Copper tungsten (tungsten-copper, Cu-W, or W-Cu) alloy is a pseudo-alloy of copper and tungsten. As copper and tungsten are not mutually soluble, the material is composed of distinct particles of one metal dispersed in a matrix of the other one. The microstructure is therefore rather a metal matrix composite than a true alloy.
