Product Description

Compared with Traditional Copper Electrode for EDM Industry

  1. Production Cost: Cost of isostatic graphite is 25% lower compared with the same volume of copper electrodes.
  2. .Easy to process: the machining speed is 3-5 tims faster than copper electrode’s, and the surface is smooth. Electric Discharge processing speed is 1/3 -2times faster than the copper electrode’s, and specially for rough machining.
  3. Machining Accuracy: good machining precision, and the C.T.E is 1/4 of copper’s.
  4. Low Weight: the density of graphite is only 1/5 of copper’s, it’s more suitable to produce larger electrode to make giant parts.

About processing and production
