USED IN PAPER AND CEMENT PLANTS
Mersen offers a wide range of metal graphite brushes, particularly adapted to asynchronous motors with wound rotor.
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.
