What is tungsten copper alloy

Tungsten and tungsten alloy composed of copper is called Copper Tungsten alloy, it is used the amount of 10% to 50%. Preparation Copper Tungsten 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.
