Tungsten copper electrode for EDM and ECM 

 

Our tungsten copper electrode for EDM and ECM is manufactured by the press, sinter, and infiltrate process. In order to reach a consistent homogeneous material giving high and even burning rates, we use virgin and excellent powders. Tungsten copper alloys are used worldwide for EDM (Electrical Discharge Machining) and ECM  (Electrochemical Machining) as electrodes. Tungsten copper is used in plunger/sinker applications where intricate definition is required.

 

Advantages:

High thermal conductivity

Low thermal expansion

High wear resistance combined

Excellent electrical conductivity

Tungsten Copper Rotary Electrode for PCD Rotary Tools Disk Erosion

 

Copper tungsten erosion wheels and copper tungsten erosion discs are also known as electrodes for erosion, or erosion electrodes. Thanks to very high melting point of tungsten, tungsten copper rotary electrodes have very long service life comparing to copper or graphite electrodes.

 

The main benefits of tungsten copper erosion wheel are as below: 

1. High conductivity and routine maintenance can ensure the stability of the working tungsten copper rotary electrodes. 

2. High thermal conductivity can help the PCD to endure the high temperature. 

3. High density can ensure the least bend destroy of the PCD blades.
