Material Notes:

TIMREX Primary Synthetic Graphite is produced in a unique highly controlled graphitization process which assures narrow specifications and unequalled consistent quality due to: monitoring of all production and processing stages, strict final inspection, and clearly defined development processes.TIMREX Primary Synthetic Graphite shows unique properties thanks to the combination of a consistent purity, perfect crystalline structure and well defined texture.Tribological and mechanical properties:Medium toughnessGood lubrication propertiesAdvantages and applications: Low friction coefficientLow wear of the counterpart Good transfer-film formationHigh electrical conductivity Suitable for pitch-bonded and resin-bonded brushes Fe-self lubricating engineering parts Fe-friction parts Copper/bronze bearings Copper friction parts copper clutch facingsInformation provided by TIMCAL
