Copper Tungsten Alloys

Refractory Metal Composites
Typical Properties

Eagle refractory metal composite materials are a combination of tungsten or tungsten carbide combined with copper or silver. The manufacturing process is to press the refractory (tungsten or tungsten carbide), sinter the pressed compact at a high temperature, and infiltrate with copper or silver. All this is done under very closely controlled conditions. The result is a relatively hard materials with superior arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity.
