W85Cu15 W80Cu20 Alloy Tungsten Plate Copper Tungsten Alloy Sheet Surface Machined
Copper tungsten alloy have high physical and mechanical properties, as well as high thermal and electrical conductivity, these properities make our copper tungsten 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
Applications of Copper Tungsten Alloy Plates:
1) Arcing contacts and vaccum contacts in high and medium voltage breakers or vaccum interruptors
2) Electrodes in electric spark erosion cutting machines
3) Heat sinks as passive cooling elements of electronic devices
4) Electrodes for Resistance Welding
We can make as your requirement
