Meeting RWMA Class 3

The beryllium and nickel in this alloy make it stronger and more rigid than pure copper

Copper Tungsten (10W3) Round Bar Length (inches):8 When used outdoorsMade of 75% tungsten for wear and arc erosion resistance and 25% copper for electrical and thermal conductivity, these bars work well for electrodes in the electrical discharge machining of tungsten carbide and other dense material. They are RWMA Class 11, so use them for facings and insets for flash and butt welding dies, projection welding electrodes, and seam welding. Compared to RWMA Class 10, they are more wear resistant because they contain more
