Electro-graphite carbon brush

Electro-graphite carbon brush is one of most important kind of carbon brush in the BOYO CARBON products. These kinds of carbon brush is most widely used in many industrial fields. These kind of carbon brush material is converted into graphite by heat treatment at a temperature of the order of 2500 ℃ . The graphite thus produced is usually known as “electro-graphite” because the high temperature is obtained by the use of thermal and electrical conductivity of graphite and is additionally very resistant to burning. Consequently electro-graphite grades are capable of carrying heavy overloads.
