Copper tungsten is composed of tungsten and copper alloy, commonly used alloy copper content of 10% to 50%. Alloy powder metallurgy method of preparation, has a good conductive thermal conductivity, good high temperature strength and a certain degree of plasticity. At very high temperatures, such as above 3000 ° C, the copper in the alloy is liquefied and evaporated, absorbing heat in a substantial amount and reducing the surface temperature of the material.
