Carbon brushes

Carbon brush leading manufacturer 

A carbon brush is a sliding contact used to transmit electrical current from a static to a rotating part, in a motor or generator, and as regards DC machines, ensure a spark-free commutation.

Carbon brushes are maintained by brush-holders to be in permanent contact with the slip ring assembly or with the commutator. Mersen offers a wide range of carbon brushes for all types of motors, generators and alternators, grounding devices and current and signal transmission.

Carbon brushes for DC motors

DC motor carbon brush Mersen

Carbon brushes for DC motors

Mersen offers a wide range of electrographitic brushes, particularly adapted to DC motors (of which globally renowned EG34D grades).

Electrographitic grades are prepared from carbon powders and coke; they are then subjected to high temperature thermal treatments (> 2500 °C) to transform the basic amorphous carbon into artificial graphite.

Carbon brushes for generators & alternators

generator alternator carbon brush Mersen

Carbon brushes for generators & alternators

Mersen offers a wide range of carbon brushes for generators and alternators.

For turbogenerators, our LFC brush grades are internationally renowned, especially LFC 554 grades.
For wind mills, CG626 grades are known throughout the world.


These soft graphite grades are prepared from graphite powders (natural purified or artificial) agglomerated with appropriate binders to give them good resistance to shocks and mechanical vibrations.

Carbon brushes for FHP motors

Carbon brushes for FHP motors

Mersen offers a wide range of carbographitic and bakelite-graphite brushes for FHP motors.

Carbographitic grades are prepared from carbon and coke powders (natural or artificial) agglomerated with appropriate binders to give them good resistance to high temperature and variable loads.

Bakelite-graphite grades are made from natural or artificial graphite powders agglomerated with a thermo-hardening resin to give them a high electrical and mechanical resistance power.

Grounding brushes

Grounding brushes

Mersen offers a wide range of brushes for grounding systems, made from metal graphite grades.

These grades are prepared from purified natural graphite and metal powders (copper, silver…) pressed and baked to bring them to the required solidity and cohesion levels. 

Carbon brushes for asynchronous motors

Carbon brushes for asynchronous motors

Mersen offers a wide range of metal graphite brushes, particularly adapted to asynchronous motors with wound rotor used in paper and cement plants.

Metal graphite brushes grades are prepared from purified natural graphite and metal powders (copper, silver…); then they are compressed and baked to bring them to the required solidity and cohesion levels.

Carbon brushes for signal & power transmission

current signal transmission brush Mersen

Carbon brushes for signal & power transmission

Mersen offers a wide range of metal graphite brushes for current and signal transmission: Pitch motor, Ward Leonar Group, annealers, etc. Metal graphite grades are prepared from purified natural graphite and metal powders (copper, silver…); then they are pressed and baked to bring them to the required solidity and cohesion levels.
