Spark Graphite is an isotropic, very fine grain graphite with high strength, high density, electrical conductivity, providing high metal removal rate, excellent surface finish, and high resistance to electrode wear makes it an excellent EDM electrode material. Spark Graphite is light in weight, dimensionally stable and is easily machinable into any size or shape from larger size EDM graphite electrode to thin and intricate EDM graphite electrodes.

Classification of EDM Graphite Electrodes	Application
Fine	Large Forging Dies , Die Casting Dies and Plastic Moulds.
Superfine	Precision Forging Dies , Die Casting ,Plastic Moulds, Rubber & Glass Moulds
Ultrafine	Very precision - Threading Electrodes, Engraving, Stamping Dies & Aerospace Applications
Angstrofine	Fine detailed Engraving electrodes, Delicate electrode & intricate Mould and Dies
