Tungsten Copper Used for EDM and ECM

tungsten copper EDM block


Due to excellent properties in arc erosion, fusion resistance, tungsten copper block is widely used as electrode materials in EDM and ECM.


Tungsten copper has good wear resistance, high MRR (Material Removal Rate) and precision, especially for tungsten carbide (WC) and other materials with high hardness machining.


Tungsten copper is widely used in EDM and ECM. EDM is a kind of process that ablate the metal by rapidly repetitional discharge. ECM including electrolytic machining, electric grinding, electrochemical polishing, electroplating and electroetching, etc.
