Copper Tungsten(CuW) Alloy
Nov 19, 2017

CuW or WCu, usually is called Copper Tungsten / Tungsten Copper Alloy, in fact, tungsten copper alloy is not a real alloy but 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.

Copper Tungsten alloy combines the properties of both metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to machine.

We are professional in manufacturing CuW electrical contacts by method infiltration. Firstly,

Pressing the tungsten particles into a desired shape, sintering the compacted part, then infiltrating with molten copper.  Electrodes  and bars of the  CuW alloy are available as well.


This type of CuW electrical contacts has a high heat resistance, low thermal expansion and high electrical or thermal conductivity. It is used to make contacts for both high and low voltage electrical devices, and for high speed steel devices and SF6 switches.
