Copper Tungsten EDM Spark Erosion Electrodes
EDM machining, or electrical discharge machining, is a relatively new machining technology known for its high efficiency in working with hard materials such as tungsten carbide cobalt hard alloy, high-speed steel, and PCD tools erosion rotary electrodes.
HOSO METAL has been operating in this field for over ten years. We specialize in producing tungsten copper electrodes, chromium copper electrodes, and tungsten silver electrodes for EDM applications.
Our copper tungsten electrodes from the "E" series are known for their high density, exceptional wear resistance, non-porous structure, good machinability, and high efficiency in EDM cutting speeds.
We provide a diverse range of WCu composite materials that offer optimal solutions for various applications. For more details, please refer to our basic and general stock sizes of copper tungsten EDM electrodes.

HOSOPM®075E is commonly used as an EDM electrode material for molding cemented carbide tools.
Copper Tungsten Triangle Bar Cemented Carbide EDM Electrode
Tungsten carbide, also known as cemented carbide, is extremely hard and challenging to machine. The most effective method for machining cemented carbide tools is EDM (electrical discharge machining).
HOSOMETAL's copper tungsten exhibits excellent internal uniformity and avoids issues with porosity. Our products offer the best combination of price and performance, making them an ideal choice for your needs.
