Electrically Conductive Tungsten Copper Bars
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
Made 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’re 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’re more wear resistant because they contain more tungsten. They’re commonly known as Elkonite bars.

Electrically Conductive Tungsten Copper Rods
- Yield Strength: Not Rated
- Hardness: Rockwell C20 (Hard)
Use these rods for electrodes in the electrical-discharge machining of dense material, such as tungsten carbide—they’re 75% tungsten for wear and arc-erosion resistance and 25% copper for electrical and thermal conductivity. Meeting RWMA Class 11, they’re suitable for facings and insets for flash and butt welding dies, projection welding electrodes, and seam welding. Compared to RWMA Class 10, they’re more wear resistant because they contain more tungsten. They’re also known as Elkonite rods.
