Five reasons to use graphite EDM electrodes –

A highly detailed EDM electrode however with critical features, extreme tolerance and stringent EDM requirements would entail a more premium graphite electrode to fit the needs of this application. On the other hand, the types of copper available on the market are few and minimize the ability to match the material characteristics to the EDM application, thus limiting optimum performance.

Best graphite for roughing

2020/12/7Metallic electrodes also generally use negative polarity, whereas EDM C3 uses positive polarity just like common high grades of graphite. We use C3 for high detail or poor flushing conditions. Since our sinkers serve a support function, rather than a primary income source, less focus is given to tweaking for optimum performance.
