EDM / ECM
Elkonite® materials are used for electrodes in electrical discharge machining (EDM) and electrochemical machining (ECM). The spark erosion resistance and good electron emission characteristics of Elkonites® make them good electron EDM electrode materials. They have excellent wear resistance, good metal removal rates and the ability to retain good detail. They are particularly good for machining tungsten carbides as other electrode materials may be inadequate. Elkonite® 3W3 is used where speed and wear resistance is important. Elkonites® 10W3 and 20S are especially outstanding on applications requiring high precision cutting and high quality surface finishes. Elkonite® 10W3 is used for ECM electrodes because it conducts high current and resists deformation and abrasion from high velocity movement of the electrolyte.
