Copper round electrodes

銅電極

Copper and copper alloys are widely used in electronics and electric wires due to their excellent corrosion resistance, superior electrical conductivity, and ease of fabricating. Especially superior electrical conductivity of copper is highly evaluated for industrial usages.
Our E. D. M. electrodes are produced with selected materials under centralized management in our facility to keep the high quality so that our customers can perform stable, high speed processing with low costs.

Brass round electrodes

Brass round electrodes

Although Brass has less electrical conductivity than pure copper, it is stronger and harder than copper and thus it does not get worn out easily during the processing. For this reason Brass is used in electrodes very often. We recommend you to choose an electrode suitable for the material to be processed.
Our E. D. M. electrodes are produced with selected materials under centralized management in our facility to keep the high quality so that our customers can perform stable, high speed processing with low costs.
