Cu25 W75 tungsten copper alloy electrode, tungsten electrode
Tungsten copper electrode for EDM and ECM
Our tungsten copper electrode for EDM and ECM is manufactured by the press, sinter, and infiltrate process. In order to reach a consistent homogeneous material giving high and even burning rates, we use virgin and excellent powders. Tungsten copper alloys are used worldwide for EDM (Electrical Discharge Machining) and ECM (Electrochemical Machining) as electrodes. Tungsten copper is used in plunger/sinker applications where intricate definition is required.
Advantages:
High thermal conductivity
Low thermal expansion
High wear resistance combined
Excellent electrical conductivity
