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, have been widely used in all AC(Alternating Current ) and DC(Direct Current) motors

2. About material original :

---- Original , From Original products manufacturer

----- Abroad one , From Abroad , eg, Germany or American , same as original carbon brush material

----- China similar one, From China local, similar to Original material

3. About difference between China Similar and Abroad one :

----- Density , resistivity , current density and max speed maybe similar or same

----- Lifetime not same . eg, Abroad one can use 1 year, China similar can be up to 6-8 monthes.
