Copper Tungsten Plate / WCu Alloy Sheet

Tungsten copper (copper tungsten, CuW, or WCu) alloy is a pseudo-alloy of tungsten and copper. 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.

Tungsten-copper alloy plate has a wide range of applications, mainly including:

Heat sinks and thermal base plates:

High power electronics, semiconductor packaging, LED lighting, aerospace, etc.
