The performance characteristics of the copper sleeve material are introduced
to be oil lubricated bearings. Is a variety of copper alloy used for mechanical parts lubrication. With SOB graphite copper sets all kinds of large, heavy machinery, is an important component on the mechanical parts.
Copper sleeve material performance characteristics:
1, ZCuSn10Pb1
High hardness, excellent wear resistance, not easy to have killed the phenomenon, a better injection molding machine copper casting performance and cutting performance in the atmosphere and fresh water self-lubricating skateboard has good corrosion resistance. Can be used for high load (20Mpa below) and high sliding speed (8m / s) work under wear parts, such as connecting rods, bushings, bearings, gears, worm gear and so on.
2, ZCuSn10Pb5
Corrosion resistance, especially for dilute sulfuric acid, hydrochloric acid and fatty acids. Structural materials, corrosion resistance, acid-resistant accessories and crusher bushings,.
3, ZCuPb10Sn10
Lubricity, wear resistance and corrosion resistance, suitable for bimetallic casting materials. Vehicle bearings, the peak load of 100Mpa internal combustion engine bimetallic bearings, as well as the piston pin sets, such as friction films.
4, ZCuPb15Sn8
In the absence of lubricants and water quality lubricant conditions, sliding and self-lubricating properties, easy cutting, casting performance is poor, the dilute sulfuric acid corrosion resistance. Surface pressure, and the pressure side of the bearing, can be used to make cold rolling mill copper cooling pipe, impact load of 50Mpa parts, internal combustion engine bimetallic pad, mainly for the maximum load of 70Mpa piston pin sets, acid accessories .
5, ZCuZn38Mn2Pb2
Has good mechanical properties and corrosion resistance, wear resistance is better, cutting performance is good. General-purpose structural parts,, ships, meters and other simple use of the casting, such as sleeve, bushings, bearing, slider and so on.
