Copper–tungsten

Copper–tungsten (tungsten–copper, CuW, or WCu) is a mixture 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 instead of a true alloy.
