ZCuPb10Sn10

Lubrication performance, wear resistance and corrosion resistant performance is good, suitable for bimetal casting materials

Surface pressure is high, and there is the lateral pressure of the sliding bearing, such as rolling rolling, vehicle use bearing, load peaks 60 mpa hit parts, as well as the highest peak of 100 mpa bimetallic bearing bush of the internal combustion engine, and the piston pin sets, lining, etc

ZCuPb15Sn8

Under the condition of lack of lubricant and use water quality lubricants, sliding and lubricating, free cutting, casting performance is poor, for dilute sulfuric acid corrosion resistant performance is good

Surface pressure is high, and the lateral pressure of bearing, copper cooling pipe can be made from cold rolling mill, impact resistance load of up to 50 mpa parts, internal combustion engines of bimetallic bearing, mainly used for the biggest load of 70 mpa of piston pin set, acid-proof accessories

ZCuPb20Sn5

At higher sliding performance, in the absence of a lubricating medium and water as medium are particularly good self-lubricating performance suitable for bimetal casting material, sulfuric acid corrosion resistance, easy cutting, casting performance is poor

High sliding speed of the bearing, and crusher, water pump, cold rolling mill bearings, piston pin load of 70 mpa

ZCuPb30

Have good self-lubrication, free cutting, casting performance is poor, easy to produce the gravity segregation

High sliding velocity of bimetallic bearing shell, wearing parts, etc
