15.6g/cm3 Tungsten Copper Alloy W80Cu20 Electrodes For Welding Machine
Introduction of Tungsten Copper Alloys
Tungsten copper alloy contains 6 ~ 50% (weight ratio) copper, which has the advantages of both tungsten and copper: Tungsten copper alloy is featured by high temperature resistance, arc ablation resistance, high strength, large ratio, good conductivity and thermal conductivity, small thermal expansion, easy cutting and sweating cooling. It is widely used in machinery, power, electronics, metallurgy, aerospace and other industries.
Specifications:
1) Materials: W30Cu, W50Cu, W70Cu, W75Cu, W80Cu, W90Cu
2) Technique: infiltering process
3) Density of tungsten copper:15.5~18.0g/cm3
4) Shape: Plate,sheet,strip,tube,rod,or machined parts
Applications of Tungsten Copper Alloys
