Electrical discharge machining - EDM

Isostatic graphite EDM - Electrical Discharge Machining

ELLOR® is a a complete range of isostatic grades, from universal to micro-grain graphite dedicated to Electrical Discharge Machining (EDM), also called Spark Machining or Die Sink EDM. ELLOR® is a global leading brand.

ELLOR® is the most comprehensive range of graphite grades for EDM on the market.

Together with the support of our application engineers, you will be able to select the right grade for your project.

7 grades

ELLOR® +18 EDM mersen

ELLOR® +18

A medium density graphite for semi-finishing and roughing operations in the least amount of time and at minimum cost.

ELLOR® +20 Mersen


A graphite for both roughing and finishing operations. Ideal for manufacturing plastic moulds.

ELLOR® +25 EDM Mersen


The greater density of this grade provides a better surface finish and its mechanical properties enhance the service life of electrodes. A graphite for universal use.

ELLOR®+30 EDM Mersen


The surface finish is better and electrode wear is always the lowest.

ELLOR®+40 EDM Mersen


The surface finish is better and electrode wear is always the lowest.

ELLOR® +50 EDM Mersen

ELLOR® +50

The very fine structure of these materials associated with their high density allows them to produce very precise machining details and a remarkable surface finish, whilst reducing electrode wear.



The very fine micro-grain structure of this graphite offers unequaled precision and performance.
