Tungsten copper electrical contacts material is a composite of tungsten and copper. W-Cu material with both tungsten low expansion characteristics, but also has copper of high thermal conductivity properties.
Heat spreader is most often having high thermal conductivity. heat spreader is a primary heat exchanger that moves heat between a heat source and a secondary heat exchanger.
Tungsten copper alloy bar is integrates the advantages of tungsten and copper, within which tungsten's melting point is higher( about 3410 ℃) and density is larger (about 19.34g/cm3).
Tungsten copper military throat insert is lining material of solid rocket motor nozzle, and its high temperature performance and ablation resistance directly affects the thrust and efficiency of the engine.
