Graphite has no melting point. It has good conductivity, excellent thermal shock resistance, and can be used for stable EDM. Graphite has excellent machinability. Compared with metal, it can be processed into electrode in a very short time, only 1/3 to 1/10 time compared to the metal.
High surface finish , High dimensional accuracy , High precision of discharge dimension , High speed of EDM , Small weight , Excellent machinability
