Spark discharge electrode also call as electrical Discharge Machining (EDM), which is a new processing technology. It can use to process material of work hard cutting, very hard material, all kind of high spped steel even diamond , ceramic, etc.

For ten years experiences, we research and develop manufacture process of tungsten copper alloy electrode of spark discharge. There are quantities of tungsten copper rods, tungsten copper plate, tungsten copper thread electrode, tungsten copper electrodes with handle, tungsten copper tube using for precision mould manufacturer.

The principle of choosing spark discharge electrode material

Firstly it is high conductivity.

Secondly it can effect to remove metal.

Thirdly, it is little consumption.

At last, it is easy to process to mould.
