Tungsten Copper Alloy in Aerospace
Tungsten copper alloy is tungsten-copper composite material with tungsten as skeleton and copper as electrically and thermally conductive phase, usually produced by powder metallurgy infiltration process. Tungsten phase gives the material relatively high melting point, hardness and ablation resistance, while copper phase facilitates current conduction and heat diffusion, enabling the material to combine high-temperature resistance, electrical and thermal conductivity, low thermal expansion and adjustable performance, and meet comprehensive requirements of aerospace equipment for thermophysical properties, electrical properties and structural stability.
