Tungsten Copper Content
Tungsten Copper Content
Tungsten copper content is the content of tungsten or copper in the alloy, the normally content for tungsten copper alloy is 10%～50%. Tungsten copper alloy powder metallurgy extraction has good electrical and thermal conductivity, good high temperature strength and a certain degree of plasticity. At very high temperatures, such as above 3000 ℃, copper alloy is liquefied evaporated absorbs heat, reduces the surface temperature of the material. So this kind of material is also referred to as metal sweating material.The Performance Table Of Tungsten And Copper Content
