Centrifugally cast copper sleeves and tin bronze can also be cast by centrifugal casting, mainly to control the rotation speed and the casting temperature.

The centrifugally cast tin bronze sleeve will not have trachoma and pores.

Copper sleeve material selection and main performance

Material recommendation

1. ZCuSn6Zn6Pb3, ZCuSn5Zn5Pb5, can be used to make bushings that work under medium load and speed. Gears, worm gears and other wear-resistant parts.

2. ZCuSn10P1 is a typical tin-phosphor bronze with high hardness and wear resistance. It can be used to manufacture parts that work under heavy load, high speed and high temperature, and are subject to strong friction, such as connecting rods. Bushings, gears, worm gears, etc.

3. ZCuAl9Mn2, ZCuAl9Fe4, and aluminum bronze have high strength, high density, and stable chemical properties. Commonly used in valve bodies, worm gears, nuts, pipe fittings, etc.

4. ZCuZn25Al6Fe3Mn3 high-strength aluminum brass has the highest strength among special brasses. It has high strength, high hardness, high wear resistance, moderate plasticity and good corrosion resistance. Therefore, it is used for high-load wear resistance in casting heavy machinery

5. ZCuSn10P1 has high hardness, excellent wear resistance, is not prone to seizure, and has good casting performance and cutting performance. It 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 rods, bushings, bearings, gears, worm gears, etc.

6. ZCuSn10Pb5 is corrosion-resistant, especially to dilute sulfuric acid, hydrochloric acid and fatty acids. Structural materials, corrosion-resistant and acid-resistant accessories as well as crusher bushings and bearings.

7. ZCuPb10Sn10 has good lubrication properties, wear resistance and corrosion resistance, and is suitable for use as bimetal casting materials. Bearings for vehicles, bimetal bearings for internal combustion engines with load peaks up to 100Mpa, piston pin sleeves, friction plates, etc.

8. ZCuPb15Sn8 has good sliding and self-lubricating properties, easy cutting, poor casting performance, and good corrosion resistance to dilute sulfuric acid in the absence of lubricants and water-based lubricants. Bearings with high surface pressure and side pressure can be used to make copper cooling pipes for cold rolling mills, parts with an impact load resistance of 50Mpa, bimetallic bearing bushes of internal combustion engines, mainly used for piston pin sleeves with a maximum load of 70Mpa, and acid-resistant accessories. .

9. ZCuZn38Mn2Pb2 has good mechanical properties and corrosion resistance, good wear resistance and good cutting performance. General-purpose structural parts, simple-looking castings used in ships, instruments, etc., such as sleeves, bushings, bearing bushes, sliders, etc.
