Introduce the performance characteristics of the copper sleeve material

The copper sleeve needs to be lubricated with oil. It is made of various copper alloys for lubrication of mechanical parts. SOB graphite copper sleeve is an important part of machinery on various large and heavy machinery.

Performance characteristics of copper sleeve material:

1. ZCuSn10Pb1

High hardness, excellent wear resistance, not easy to cause seizure, better casting performance and cutting performance than the copper sleeve of injection molding machine, self-lubricating slide plate has good corrosion resistance in the atmosphere and fresh water. It can be used for wear-resistant parts under high load (below 20Mpa) and high sliding speed (8m/s), such as connecting rods, bushings, bearings, gears, worm gears, etc.

2. 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 bushings and bearings.

3. ZCuPb10Sn10

Good lubrication, wear resistance and corrosion resistance, suitable for bimetal casting materials. Vehicle bearings, internal combustion engine bimetallic bearings with a peak load of 100Mpa, piston pin sleeves, friction plates, etc.

4. ZCuPb15Sn8

In the absence of lubricants and water-based lubricants, it has good sliding and self-lubricating properties, easy cutting, 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 of cold rolling mills, parts with impact resistance up to 50Mpa, bimetallic bushes for internal combustion engines, mainly used for piston pin sleeves with a maximum load of 70Mpa, and acid-resistant parts .

5. ZCuZn38Mn2Pb2

It has good mechanical properties and corrosion resistance, good wear resistance, and good cutting performance. General purpose structural parts, simple castings used in ships, instruments, etc., such as sleeves, bushings, bearings, sliders, etc.
