Tungsten copper alloy bar electrode

By selecting high purity tungsten powder and oxygen-free copper, all of our tungsten coppers are produced by sintering and infiltrating process. 1. The composition of tungsten and copper are well-proportioned and accurate percentaged; 2. Tungsten coppers are precisely machined with high thermo stability, high arc resistance and high strength; 3. Copper tungstgen has high electrical conductivity and thermal conductivity;
