Electrodes 14.5g/Cm3 W75Cu25 Copper Tungsten Alloy Parts
Tungsten Copper alloy Properties:
Tungsten copper alloy has some advantages of both tungsten and copper. It has the characteristics of high temperature resistance, arc burning resistance, high strength, large ratio, good conductivity and thermal conductivity, small thermal expansion, easy processing, etc.
Tungsten alloy: we can produce kinds of specification(WNiFe,WNiCu and Tungsten Carbide Alloy)
Tungsten copper alloy applications:
Tungsten copper alloy is widely applied in welding electrode, arc contact and vacuum contact of high and medium voltage circuit breaker, EDM electrode and other industries.
