Tungsten copper is produced with the selection of fine tungsten and copper powder, and soaked by the first-class sintering refining process. Combined with the advantages of tungsten and copper, it has the characteristics of high temperature resistance, erosion, high strength, heavy, good conductivity, being easy to machine and transpiration cooling. It can be used as electrical contacts, electrodes, for electronic packaging, and in other occasions which require of thermal conductivity properties and high temperature.
