Our copper tungsten alloys have high physical and mechanical properties, 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

 we can produce the copper tungsten by optimized the tungsten composition down to 15 wt.% , up to 90 wt.% base on application requirement. Surely the phyicial properities can be enhanced base on the requirment. Our products grade equivalent to 1W3, 3W3, 5W3, 10W3, 30W3.
