EDM Graphite - Grade G3

Electrical Discharge Machining Graphite Grade G3
G3 is a fine grain isotropic EDM Graphite which is suitable for EDMing of plastic moulds. G3 is usually employed in the roughing EDM process. It can also be employed in the finishing EDM process in certain applications involving large cavity electrodes.

  • Forging dies
  • Diecast moulds
  • Plastic moulds
  • High metal removal rates
  • Low wear roughing to mid-range EDM electrodes


DM Graphite Grades are designed to span the range of application conditions from high metal removal rates to fine detail finishing.
