EDM-200® Graphite

An isotropic, Superfine graphite providing good strength, surface finish, and wear resistance. 

  • Average particle size of less than 10 microns providing good strength, surface finish, and resistance to damage
  • Excellent metal removal rate improves throughput
  • Good resistance to wear increases time between replacements
  • Provides excellent repeatability from electrode to electrode and from job to job

Available for order as billets, semi-finished rods, blocks, and plates.
