Copper sleeve material is as follows:

ZCuSn10Pb1

High hardness, excellent wear resistance, not easy to produce biting phenomenon, has better casting performance and cutting performance, and has good corrosion resistance in the atmosphere and fresh water.

It can be used for wear-resistant parts working under high load (below 20Mpa) and high sliding speed (8m/s), such as connecting rod, bushing, bearing bush, gear, worm gear, etc.

ZCuSn10Pb5

Corrosion resistance, especially to dilute sulfuric acid, hydrochloric acid and fatty acids.

Structural materials, corrosion-resistant, acid-resistant accessories and crusher bushing, bearing.

ZCuPb10Sn10

Good lubrication, wear resistance and corrosion resistance, suitable for use as bimetal casting materials.

Bearings for vehicles, bimetal bearing bushing of internal combustion engine with peak load up to 100Mpa, piston pin sleeve, friction plate, etc.

ZCuPb15Sn8

In the absence of lubricants and water lubricants, sliding and self-lubrication performance is good, easy cutting, casting performance is poor, corrosion resistance to dilute sulfuric acid is good.

Bearing with high surface pressure and side pressure, can be used to make copper cooling pipe of cold rolling machine, parts with impact load of 50Mpa, bimetal bearing bush of internal combustion engine, mainly used for piston pin sleeve with maximum load of 70Mpa, acid resistant accessories.

ZCuZn38Mn2Pb2

It has good mechanical properties and corrosion resistance, good wear resistance and good cutting performance.

General purpose structural parts, ships, instruments and other use of the appearance of simple castings, such as sleeves, bushings, bearings, sliders, etc.
