Tungsten Copper Rod for EDM

Tungsten copper is widely used for electrical discharge machining (EDM) because of its combination of electrical conductivity, high-temperature resistance and wear resistance.

Tungsten copper rods can be machined into:

• EDM electrodes

• EDM electrode blanks

• Spark erosion electrodes

• Precision EDM components

Different WCu compositions can be selected according to the required electrical conductivity, hardness and wear resistance.

Tungsten Copper Rod for Electrical Contacts

WCu rods are also used as raw material for electrical contact components.

The combination of tungsten's high melting point and copper's excellent electrical conductivity makes tungsten copper suitable for applications involving:

• High electrical current

• Arc resistance

• Electrical switching

• High-temperature electrical contacts

• Resistance welding

Tungsten Copper Rod for Resistance Welding

Tungsten copper is suitable for selected resistance welding electrodes and welding components.

The material provides a useful balance of:

• High-temperature resistance

• Electrical conductivity

• Thermal conductivity

• Wear resistance

• Arc resistance

The appropriate WCu grade depends on the welding current, temperature, pressure and operating conditions.

Tungsten Copper Material

Tungsten copper is a metal matrix composite rather than a conventional tungsten-copper alloy formed by melting the two metals together.

The material is commonly manufactured using powder metallurgy and copper infiltration processes.

A typical production process is:

Tungsten Powder → Powder Pressing → Sintering → Copper Infiltration → Machining → Grinding → Inspection

The final material properties depend on the tungsten content, manufacturing process and processing conditions.
