Our major product of copper tungsten sheet, copper tungsten
plate, block and bar is very popular used as EDM electrode. This material has
both tungsten and copper's character, for example: copper is good for
electrical conductivity, tungsten is good for the hardness. Our copper tungsten
plate for EDM is made by vacuum infiltration technology. Which product has very
good physical and mechanical properties with excellent wear resistance.
Our copper tungsten plate has below advantage:
-Maturity press- sinter- infiltration process.
-high electrical conductivity gets high erosion speed.
