Copper sets of materials Features:
1, ZCuSn10Pb1
High hardness, excellent wear resistance, not easy to produce galling, have more injection molding machines copper sets of good casting performance and cutting performance, in the atmosphere and water in the self-lubricating slide has good corrosion resistance. For high load (20Mpa less) and high sliding speed (8m / s) working under wear parts, such as connecting rod, bushings, bearings, gears, worm gears.
2, ZCuSn10Pb5
Corrosion, especially for sulfuric acid, hydrochloric acid and fatty acids. Structural materials, corrosion, acid-proof accessories and crusher bushings, bearings.
3, ZCuPb10Sn10
Lubricating properties, good wear resistance and corrosion resistance, suitable for use as bimetal casting material. Vehicles bearing, engine load peak of 100Mpa bimetal bearing, and piston pin bushings, friction plates and so on.
4, ZCuPb15Sn8
In the absence of lubricants and lubricant use under conditions of water quality, good sliding properties and self-lubricating properties, easy cutting, casting performance is poor, good corrosion resistance to sulfuric acid. Surface pressure is high, there are side pressure bearing, it can be used to manufacture copper cooling tubes cold rolling mill, impact-resistant negative Heda bimetal bush 50Mpa parts, internal combustion engines, mainly for the largest negative Heda 70Mpa piston pin bushings, acid Accessories .
5, ZCuZn38Mn2Pb2
It has good mechanical properties and corrosion resistance, good abrasion resistance, good machinability. It looks simple casting structure general purpose ships, such as the use of instruments, such as sleeves, bushings, bearings, sliders and so on.
