Characteristics: tungsten copper is a kind of composite material made by static pressing, high temperature sintering and copper dissolving, which takes advantage of the excellent metal properties of high-purity tungsten powder and the plasticity and high conductivity of high-purity copper powder. Good arc breaking performance, good conductivity and heat conduction, small thermal expansion, no softening at high temperature, high strength, high density and high hardness.

The copper content of common alloys is 10% - 50%. The alloy is made by powder metallurgy. It has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At a very high temperature, such as above 1500 ¡É, the copper in the alloy is liquefied and evaporated, which absorbs a lot of heat and reduces the surface temperature of the material. So this kind of material is also called metal perspiration material. Tungsten copper alloy has a wide range of applications, mainly used to make high-voltage electrical switch contacts and rocket nozzle throat lining, tail rudder and other high-temperature components, also used as electrical machining electrode, high-temperature mold and other occasions requiring electrical conductivity and thermal conductivity and high-temperature use.
