data sheet of carbon brush/electric brush materials

Carbon brush material, also called electric brush material, can be used for generators or electric motors; electrical machinery and carbon brushes. Carbon brush material is a kind of graphite materials we produce.

There are mainly 5types of carbon brush materials, Main types:
1). Metal graphite material.
2). Silver graphite material
3). Pure graphite
4). Resin graphite material
5). Electric graphite material

See the full data sheet of all the grades carbon brushes/electric bruses material bellow:
