Our copper tungsten alloys have high physical and mechanical property, as well as high thermal and electrical conductivity. Our copper tungsten made by the PSI(Press- Sinter-Infiltration) process. We make the copper tungsten properities base on our cusotmer's application. Our materials very suitable for EDM electrode, the die inserts and electrode facing. Our Copper tungsten alloy are designated as  ASTM B702, RWMA Class 10, RWMA Class 11, RWMA Class 12, GB/T8320-2003
