EDM-C3® Graphite

EDM-C3® graphite is a premium, Ultrafine grade graphite infiltrated with copper. This grade is unequaled for fabrication of fragile electrodes.

  • Average particle size of less than 5 microns provides high strength and resistance to damage
  • Infiltrated with copper to decrease electrical resistivity maximizes energy output for manufacturing of difficult materials
  • Provides the optimal performance of speed, wear, and surface finish to balance production speed and product lifetime
  • Ideal for electrode fabrication in subprime conditions such as poor flushing or when the operator is inexperienced 

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