Copper Tungsten (10W3) Square Bar beryllium copper but not as conductive

but not as conductive

so they’re used for molds and cavities

as well as for navigational tools

Also known as RWMA Class 2 chromium copper

Copper Tungsten (10W3) Square Bar beryllium copper but not as conductiveMade 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
