Silver graphite material | carbon brush materials- manufacturer in China

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 the second type of carbon brush material: Silver graphite material. We will show the data sheet of silver graphite material in details.

Silver graphite material, usually used in big ship or expensive machines.

application: d.c. generators with low voltage and slip rings of a.c. asynchronous motors; Slip rings of synchonorous generators, wind driven generators; Automobile starters and exciting slip rings of synchronous machines
