CuW electrode for cemented carbide EDM

EDM machining is the electrical discharge machining process. It is quiet new machining technology especial high efficiency for the hard material for example tungsten carbide cobalt hard alloy, high speed steel, and PCD tools erosion rotary electrode.

copper tungsten barHOSO METAL is working in this field more than ten years. we dedicate to produce the tungsten copper electrode, chromium copper electrode, tungsten silver electrodes for the EDM application.

Our copper tungsten electrodes are designed by “E” series are distinguished by their high density, high wear resistance and no porosity structure, good machinability and high efficiency EDM cutting speed.

We offer a wide range of WCu composite materials covering the most suitable solution for your individual application. copper tungsten EDM electrode basic and general size in stock
