Grinding Wheel Used High Electric Conductivity Tungsten Copper Electrode.EDM Electrode

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.

Application
Copper tungsten electrodes and tungsten silver electrode are widely used for machining tungsten carbide, PCD tools and high speed steel. The electrical conductivity increases with the amount of copper and the electrode wear increases with the amount of tungsten. The majority of copper tungsten electrodes for EDM is a 70% tungsten, 30% copper mixture. (except rolled sheet which is 60% tungsten, 40% copper. ) Other mixtures are available such as 80% tungsten, 20% copper; 75% tungsten, 25% copper, etc.

Advantages

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.

4.Low thermal expansion

5.High wear resistance combined

6.Excellent electrical conductivity

7.high burn-off resistance

8.excellent processing performance
