Product Description
1. About material :
Aobo Carbon provide carbon brushes in all kinds of applications for OEM customers and end users. Our customers have proven the good quality can keep in long -term use. We are sure to offer you the suitable material.
Graphite material ---- for slip ring of high-speed turbine.
Metal graphite material --- for high load and low voltage motors with less commutation task.
Resin bonded graphite material--- for small and middle sized DC(Direct Current) motors and generator plant.
Electro graphite material -----has excellent commutating performance and self-lubricated functions, ha been widely
used in all AC(Alternating Current ) and DC(Direct Current) motors that achieve not only
product life but also low wear of commutator or slip ring.
