CNC Machined W30Cu70 Copper Tungsten Alloy EDM Wheel Parts
Tungsten Copper alloy Properties:
Our tungsten copper has the advantages of high conductivity, high hardness, high temperature resistance strength and ductility and high thermal conductivity. At the same time, because we use the vacuum infiltration process, our tungsten copper alloy products are uniform without holes.

Tungsten copper alloy applications:
Tungsten copper alloy has wide applications. Tungsten copper alloy
is widely used to manufacture switch contact for high-voltage
electrical appliances, rocket nozzle throat liner and sternpost
rudder, and other high temperature components and parts. In
addition, it also can be used to make electrode for spark
processing, high temperature mold and other high heat and
electrical conductive parts. And also WCu alloy can be applied as
electrodes for electrical machining.
We can customize and produce tungsten copper alloy products according to the customer's drawings. The main application fields are resistance welding electrode, spot welding electrode, electrical contact, packaging heat sink, etc.
