Mersen offers a wide range of metal graphite brushes for current and signal transmission.
Power transmission groups applications of Mersen's carbon brushes where a current shall be passed between two elements in rotation with respect to each other: annealers, electrolytic treatment lines, Ward Leonard groups, 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.
Mersen also supplies carbon brushes for transmitting signals, such as data collection from a production line, command signals for a robot or the windmill pitch motor, etc.
