Refractory Metal Composites Typical Properties
Refractory Metal Material Typical Properties
The refractory-metal composite material is a combination of tungsten or tungsten carbide, and the copper or silver. The manufacturing process is extruded at a high temperature refractory material (tungsten or tungsten carbide), the sintered compact, infiltration with copper or silver is pressed. All of which are carried out under very strictly controlled conditions. The result is the formation of a super-arc, and wear resistance, high physical properties as well as high temperature resistance, good electrical and thermal conductivity, a relatively hard material.Tungsten Copper Alloy Properties
