Copper tungsten is very popular used in the EDM, since it has both tungsten and copper's character so it has very good wear resistance. Our copper tungsten plate for EDM is made by vacuum infiltration technology. which has very good physical and mechanical properties.
Our copper tungsten plate has below advantage:
1 Maturity press- sinter- infiltration process without any porosity issue.
2 high electrical conductivity get rapid cutting speed
