Tungsten copper (Cu-W) Alloy is the composite of tungsten and copper which own he excellent performance of tungsten and copper. It is used widely in such industries as engine, electric power, electron, metallurgy, spaceflight and aviation.
Tungsten copper alloy combines the properties of both tungsten and copper metals, resulting in a material that is heat-resistant, ablation-resistant, highly thermally and electrically conductive, and easy to be machined.
