OUR PRODUCTE.D.M GRAPHITE

E.D.M GRAPHITE

Electrical Discharge Machining (EDM), the dominant (EDM) electrode material displacing copper and copper alloy materials.

Graphite has many advantages that made it material used for EMD electrode:

  • Machinability
  • high Resistant to thermal shock
  • Low coefficient of thermal expansion (3 times lower than copper).
  • It does not melt, goes directly from solid state to gaseous state.
  • Density 5 times lower than copper
  • it provides a higher metal remove rate than copper.
  • Unique characteristic that the wear ratio tends to decrease as the peak current increases
