Hogen Industries refractory metal composite materials are a combination of tungsten or tungsten carbide and 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 of this is done under very closely controlled conditions. The result is a relatively hard material with superior arc and wear resistance, high physical properties at elevated temperatures, and good electrical and thermal conductivity.
The mechanical and physical properties vary with composition. The thermal and electrical conductivity increase with the amount of copper and silver, while the hardness, strength, and resistance to mechanical wear increase with the amount of tungsten or tungsten carbide. The application determines the material choice.
