Carbon brush material, also called electric brush material, can be used for generators or electric motors; electrical machinery; carbon brushes.
There are mainly 5types of carbon brush materials, Main types: Metal graphite material; Silver graphite material; pure graphite material; resin graphite material and electric graphite material. Here we will introduce another type of carbon brush materials: Pure graphite material. We will show the data sheet of pure graphite material and its application.
Pure graphite material:
application: Steel Slip rings for high speed steam turbo-generators; Especially suitable for slip rings of large turbo-generators
See the data sheet of Pure graphite material bellow:
