Product Description

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
