Our tungsten copper electrode has high physical and mechanical properties, which can answer the need of PCD rotary tools disk erosion machining. We pay a lot of effort to research and develop and optimize our process, so that we develop quantity of products for such application. Our tungsten copper alloys are complied with ASTM B702, RWMA Class 10, RWMA Class 11, RWMA Class 12 and GB/T8320-2003
