eromobil^® electrodes

Electrodes for every scenario.

Hollow electrodes are the heart of precise EDM processes – they combine maximum efficiency with impressive precision. Whether made of pure copper or in a robust tungsten-copper version, they ensure that sparks become form.

Hollow electrodes

Copper

Hollow copper electrodes offer high thermal conductivity and are particularly suitable for applications with low thermal stress.

Tungsten-copper

Tungsten-copper hollow electrodes combine the hardness and heat resistance of tungsten with the good conductivity of copper, making them ideal for high-current applications.
