Ellor®: Blöcke und Rohlinge aus hochdichtem isotropem Graphit für Ihre Funkenerosionselektroden
Graphit für EDM
Graphit hat viele Vorteile und ist dadurch das meistverwendete Material für Funkenerosionselektroden:
- Beständigkeit gegen Temperaturschocks
- Geringer Wärmeausdehnungskoeffizienten und hervorragende geometrische Stabilität
- Bearbeitbarkeit
- Geringer Verschleiß während der Funkenbildung
Mersen ist in der Lage, für die jeweilige Kundenanforderung die beste Graphitsorte mit dem besten Qualitäts-Leistungs-Verhältnis anzubieten. -

-
Ellor® 30
Exceptional superfine grain grades
The surface finish is better and electrode wear is always the lowest.
-
Ellor® 40
Exceptional superfine grain grades
The surface finish is better and electrode wear is always the lowest.
-
Ellor® 50
Exceptional superfine grain grades
Very fine structure and high density: very precise machining details and remarkable surface finish, whilst reducing electrode wear.
-
Ellor® DS4
The premium ultrafine grain graphite
Exceptional surface finish, outstanding strength and wear resistance.

ELLOR® isostatic graphite from Mersen has numerous advantages, making it the preferred material being used for die-sink electrodes.
- It is easy to machine.
- It is very resistant to thermal shock.
- It has a low coefficient of thermal expansion (3 times lower than copper) which guarantees stability of electrode geometry during EDM.
- It does not melt, but goes directly from the solid state to the gaseous at 3400°C, which reduces wear.
- Its density is 5 times lower than that of copper, which results in lighter electrodes.
- It provides a higher metal removal rate than copper with less wear.
- It has the unique characteristic that the wear ratio tends to decrease as the peak current increases.
