Carbon brushes for power transmission
Graphite brush for current and signal transmission: pitch motor, Ward Leonard group, annealers...
Mersen offers a wide range of metal graphite brushes for current and signal transmission.
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.
