1. About mater ial :
Aobo Carbon provide carbon brushes in all kinds of applications for OEM customers and end u s ers. Our customers have proven the good quality can keep in long -term use. We are sure to offer you the suitable mater ial .
Graphite mater ial ---- for slip ring of high-speed turbine.
Metal graphite mater ial --- for high load and low voltage motors with less commutation task.
Resin bonded graphite mater ial --- for small and middle sized DC(Direct Current) motors and generator plant .
Electro graphite mater ial ----has excellent commutating performa n ce and self-lubricated fu n ctions, 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.
