Centrifugal casting is a technology and method of injecting liquid metal into a high-speed rotating mold, so that the liquid metal can be filled with a centrifugal motion to form a casting. Due to the centrifugal motion, the liquid metal can fill the mold well in the radial direction and form the free surface of the casting; a cylindrical inner hole can be obtained without a core; it is helpful for the exclusion of gas and inclusions in the liquid metal; it affects the metal Crystallization process, thereby improving mechanical and physical properties of castings.

Product Performance

Copper sleeve material selection and main performance

Material recommendation (the following is the company's commonly used material production)

1. ZCuSn6Zn6Pb3, ZCuSn5Zn5Pb5, can be used to manufacture bushings, gears, worm gears and other wear-resistant parts that work under moderate loads and speeds.

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 rod bushings, gears, worm gears, etc.

3. ZCuAl9Mn2, ZCuAl9Fe4, aluminum bronze has 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, with the highest strength among special brass. It has high strength, high hardness, high wear resistance, moderate plasticity and good corrosion resistance. Therefore, it is used to cast high-load wear-resistant weight on heavy machinery.

5. ZCuSn10P1 has high hardness, excellent wear resistance, is not easy to cause seizure, has good casting performance and cutting performance, and has good corrosion resistance in the atmosphere and fresh water. It can be used for wear-resistant parts that work under high load (below 20Mpa) and high sliding speed (8m/s), such as connecting rods, bushings, bearing bushes, gears, worm gears, etc.
