260HB Hardness W90Cu10 Tungsten Copper Alloy High-voltage Discharge Electrodes
Tungsten Copper alloy Properties:
Tungsten copper alloy has the advantages of high conductivity, high hardness and high thermal conductivity. At the same time, because we use the vacuum infiltration process, our tungsten copper alloys are uniform without holes.
Tungsten copper alloy applications:
Tungsten copper alloy is widely applied in industrial fields such as electric spark discharge electrode, resistance welding electrode, high temperature resistant parts and so on.
