Tungsten copper ring have high physical and mechanical
properties, as well as high thermal and electrical conductivity, these
prosperities make our materials very suitable for the die inserts and electrode
facing.
Our copper tungsten alloys are designated as ASTMB702, RWMA
Class 10, RWMA Class 11, RWMA Class 12, and GB/T8320-2003.
