Copper tungsten materials,Copper Tungsten Electrical Contacts,WCu Electrode material

Tungsten copper alloy is an alloy of tungsten and copper. Commonly used copper content of the alloy is 10% to 50%. Preparation of alloy powder metallurgy method has good electrical and thermal conductivity, good high temperature strength and a certain plasticity. At very high temperatures, such as above 3000 ℃, the alloy of copper is liquefied and evaporated to absorb a lot of heat, reducing the surface temperature. So this kind of material is also referred to as metal sweat material.
