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.
