Tungsten Copper EDM Electrode

Around the globe, tungsten-copper alloy (WCu) composites are utilized in the EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) electrodes. Quality and uniformity in burning rates are achieved by employing virgin powders and through the press, sinter, and infiltrate technique. Sintered and infiltrated electrodes are made from a composite of tungsten and copper. This is because tungsten is strong, has a high density, has a high melting point, and copper has good electrical properties and is resistant to DC arcing. This combination creates a great composite. Tungsten-copper composites are utilized in plunger/sinker applications where precision and intricacy are essential, especially with tungsten carbides. Tungsten-copper composites utilized in EDM and ECM applications excel in scenarios where fine surface finishes, deep and narrow slots, and small, precise holes are of utmost importance.
