Copper tungsten erosion wheels and discs

Copper tungsten erosion wheels and discs

We offer copper tungsten electrodes also known as electrodes for erosion, or erosion electrodes, W/Cu wheels. Thanks to very high melting point of tungsten, W/CU (or CuW) electrodes have very long service life comparing to copper or graphite electrodes. Main WCu erosion wheel benefits are high wear resistance, outstanding surface quality, great machinability.

Our W/Cu electrodes are mostly used with Walter, Vollmer, Lach, Enokida and other EDM machines. They are also called PCD electrodes, copper tungsten electrodes, electrodes for EDM machines, tungsten copper EDM electrodes.

We are able to offer cup electrodes, electrode wheels or any other W/Cu erosion discs according to your requirements.
