Tungsten-Copper Alloy
Tungsten-copper alloy is an alloy composed of tungsten and copper. The copper content of common alloys is 10% to 50%. The alloy is prepared by powder metallurgy method and has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At very high temperatures, such as above 3000 ° C, the copper in the alloy is liquefied and evaporated, which absorbs a large amount of heat and lowers the surface temperature of the material. So this type of material is also known as metal sweating material.
Since the two metals of tungsten and copper are incompatible with each other, the tungsten-copper alloy has low expansion property of tungsten, abrasion resistance, corrosion resistance, high electrical and thermal conductivity with copper, and is suitable for various mechanical processes.
