Graphite products Graphite seals for various purposes. Inserts for bearings   Antifriction burned materials of АО-2500, АО-1500 brands

Antifriction burned materials of АО-2500, АО-1500 brands

Our enterprise produces antifriction burned materials of АО-2500 and АО-1500 types. These materials are applied to manufacturing of machine assemblies, working without of lubricant. Carbon-graphites of these types due to the manufacturing technology have better strength characteristics compared to that ones of graphite materials of AG type, that results in their compatibility for conditions of higher specific pressure up to 25 MPa. Maximum operation temperature in oxidative media for carbon-graphites АО-2500 and АО-1500 types is 400°С.

Our enterprise produces workpieces and end products made of them, which are approved with quality certificates.
