Tungsten copper alloy rods and bar electrodes from EJ Carbide have good resistance to high temperature, bending strength, and wear resistance. Tungsten copper alloy rods and bar electrodes are mainly using as ERW (Electric resistance welding) electrode, EDM (Electrical discharge machining) electrode, High-pressure discharge tube electrode, and so on.
High-pressure discharge tube electrode: When the high-pressure vacuum discharge tube working, the contact material temperature rises several thousand degrees Celsius in a few seconds. Tungsten copper alloy rods and bars electrodes provide the necessary conditions for the discharge tube to stabilize working since the tungsten copper has a high resistance to ablation, high toughness, good electric conductivity, and thermal conductivity
