The selection of copper sleeves is as follows:
ZCuSn10Pb1
High hardness, excellent wear resistance, less prone to biting, good casting and cutting performance, and good corrosion resistance in the atmosphere and fresh water.
Wear resistant parts that can be used for high loads (below 20Mpa) and high sliding speeds (8m/s), such as connecting rods, bushings, bearing shells, gears, worm gears, etc.
ZCuSn10Pb5
Corrosion resistant, especially for dilute sulfuric acid, hydrochloric acid, and fatty acids.
Structural materials, corrosion-resistant and acid resistant accessories, as well as crusher liners and bearing shells.
ZCuPb10Sn10
Good lubrication, wear resistance, and corrosion resistance, suitable for use as bimetallic casting materials.
Bearings for vehicles, bimetallic bearing shells for internal combustion engines with a peak load of 100Mpa, as well as piston pin sleeves, friction plates, etc.
ZCuPb15Sn8
In the absence of lubricants and the use of water-based lubricants, the sliding and self-lubricating properties are good, easy to cut, poor casting performance, and good corrosion resistance to dilute sulfuric acid.
Bearings with high surface pressure and side pressure can be used to manufacture copper cooling pipes for cold rolling mills, parts that can withstand impact loads up to 50Mpa, bimetallic bearings for internal combustion engines, mainly used for piston pin sleeves with maximum loads up to 70Mpa, and acid resistant accessories.
ZCuZn38Mn2Pb2
It has good mechanical properties and corrosion resistance, good wear resistance, and good cutting performance.
General purpose structural components, castings with simple appearance used in ships, instruments, etc., such as sleeves, bushings, bearings, sliders, etc.
