The electric brush material has the material composition of carbon powder 95-99.5 wt% and carbon fiber 0.5-5 wt%. Its production process includes mixing spray carbon black, semi-reinforcing carbon black, scale graphite and adhesive, rolling into sheet, milling and sieving to produce carbon powder component; powdering carbon fiber component, mixing the carbon powder component and carbon fiber component, pressing to form, roasting and graphitization. The electric brush produced with the material has unlimited sizes, low wear loss and powerful spark inhibiting capacity. The electric brush material is suitable for large-powre DC electric machines.
