EDM-3® Graphite

Our EDM-3® is an Ultrafine graphite that offers high strength with outstanding wear and fine surface finish characteristics easily machined to thicknesses of 0.1 mm or less.

  • Average particle size of less than 5 microns provide high strength and resistance to damage
  • Fine surface finish reduces imperfections and allows for detailed machining of intricate
  • Excellent metal removal rate shortens production times and increases productivity
  • Improved wear-resistance characteristics extend product life, minimizing replacements and downtime

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