What Material Is Used For Sinker EDM Electrodes

Sinker Electrical Discharge Machining (EDM), also known as die-sinking EDM, is a precision manufacturing process that uses electrical discharges to erode material into a desired shape. The choice of electrode material is critical, as it directly impacts machining speed, wear resistance, surface finish, and cost. Here are the primary materials used for sinker EDM electrodes, each selected for its unique properties and advantages.
