Tungsten Copper Bar Picture
W50 tungsten copper bar mainly used in relays, high voltage switches, circuit breakers and other higher demands of electrical and thermal conductivity, arc erosion resistance. In addition, it can also use as the electrode of resistance welding due to its excellent properties, such as heat resistance, arc erosion resistance, high strength, high density, good conductivity, low coefficient of expansion, easily to be cut and sweat cooling, etc.
