What are the concepts of tungsten and copper?

W-Cu alloy is an alloy of tungsten and copper. The copper content of common alloys is 10% ~ 50%. The alloy is made of powder metallurgy, which has good electrical and thermal conductivity, good high temperature strength and certain plasticity. At a very high temperature, such as above 3000℃, 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 material is also called metal sweating material.

Tungsten-copper composite is a two-phase pseudoalloy mainly composed of tungsten and copper, and it is a metal-based composite. Because the physical properties of copper and tungsten are very different, they can't be produced by melting and casting, and powder alloy technology is generally used.

Tungsten-copper alloys are widely used in aerospace, aviation, electronics, electric power, metallurgy, machinery, sports equipment and other industries. Secondly, it will also be used to manufacture high-voltage electrical switch contacts with arc ablation resistance, high-temperature components such as rocket nozzle throat liner and tail rudder, as well as electric machining electrodes, high-temperature molds and other occasions that need electrical and thermal conduction and high-temperature use.
