Copper sleeve material as follows: 
ZCuSn10Pb1 
High hardness, excellent wear resistance, easy to produce galling, better casting performance and cutting performance, good corrosion resistance in the atmosphere and fresh water. 
Can be used for high load (20Mpa or less) and high sliding speed (8m / s) working wear parts, such as rods, bushings, bearings, gears, worm gears. 
ZCuSn10Pb5 
Corrosion resistance, especially sulfuric acid, hydrochloric acid, and fatty acids. 
Structural materials, corrosion, acid and accessories as well as crusher bush, bush. 
ZCuPb10Sn10 
Lubricating properties, good wear resistance and corrosion resistance, suitable for bi-metal casting material. 
Vehicles bearing, engine load peaks reached 100Mpa bimetallic bearing, and piston pin sets, friction plates and so on.
ZCuPb15Sn8 
In the absence of lubricants and lubricant condition with lower water quality, good sliding properties and self-lubricating properties, cutting, poor casting properties, good corrosion resistance to sulfuric acid. 
Surface pressure is high, there are side pressure bearing, cold rolling mill used to manufacture copper cooling pipes, impact-resistant negative Heda bimetal bush 50Mpa parts, internal combustion engines, mainly for the maximum negative Heda 70Mpa piston pin sets, acid Accessories . 
ZCuZn38Mn2Pb2 
Has good mechanical properties and corrosion resistance, good abrasion resistance, excellent cutting performance. 
Looks simple casting structure general purpose, ships, instruments and other uses, such as sleeves, bushings, bearings, sliders, etc..
