EDM electrode / carbon / process

Product Development

SGL Group has more than 100 years of experience in the manufacture of carbon electrodes. Over the years we have worked to increase the quality of our amorphous carbon electrodes.

In our technology center in Meitingen our continues improvement efforts ensure that our electrodes meet the ever-growing requirements of our customers.
Product Requirements

In order to ensure the best results, electrodes must have the following characteristics:

Good electrical conductivity,
in order to withstand the high current density required by the metallurgical process

Good thermal conductivity,
to minimize the temperature differences inside the electrodes
when in use and, consequently, to reduce internal stresses
