The requirements for tungsten copper electrode materials are:

Mar 09, 2017

1) requires tungsten copper material not only has a good conductive thermal conductivity, but also with the best possible anti-spark corrosion effect.

2) In order to ensure the stability of EDM process and improve the utilization of electrode materials, tungsten and copper materials are required to have high material uniformity and compactness, and it is difficult to meet the requirements by conventional electrical contact preparation method.

3) EDM electrodes need to be processed according to the requirements of the mold or product to provide the corresponding shape of the tungsten copper electrode. Some of the slender bar, and some of the complex shape of the profile, not only the variety of specifications and each electrode needs smaller. Therefore, the preparation of the electrode is more complicated and difficult.
