This refractory metal composite materials are a combination of tungsten combined with copper or silver. The manufacturing process is to press the refractory, 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.

They are mainly used for making finished tungsten wire, rods and plates and additives to precision alloys.
They are mainly for electrical light sources, electrical contacts for vacuum coated films and heating elements, etc.
