1: high electrical conductivity
2: typic tungsten from 30% to 85%
Our tungsten copper alloy have high physical and mechanical properties1: composition of tungsten30 wt.%-90 wt.% copper: balance
Our tungsten copper alloy have high physical and mechanical properties, as well as high thermal and electrical conductivity, these properities make our tungsten copper materials very sutitable for the die inserts and electode facing. Our Copper tungsten alloy are designated as ASTMB702, RWMA Class 10, RWMA Class 11, RWMA Class 12, GB/T8320-2003
