Copper Tungsten Rotary Electrode for PCD and PCBN erosion

Our copper tungsten rotary electrode has high physical and mechanical properties to answer the PCD tools / disk erosion need. Great efforts have been spent to research into and optimize our process to develop quality product for this application.

Longer life and fine surface roughness for your PCD tools!
1. High conductivity and routine maintenance allows stable performance of tungsten copper electrodes.
2. High thermal conductivity helps PCD to endure high temperature.
3. High density ensures the least bend destroy of PCD blades.
