The C93200 (SAE660RG7) is considered a "standard" type of bearing material for lead-tin bronze. The alloy has excellent machining properties, good hardness, strength and wear resistance, and excellent wear resistance. Typical applications include bearings, gaskets, bushing, auto parts, main shaft bearing, machine tool bearings, crane bearing, trunnion bearing, roller bearing neck, rolling mill bearings, the sleeve is the fuel pump and pump shaft sleeve, diesel engine piston pin bushing, forging toggle lever bearing, stuffing box hydraulic press, hydraulic press mainlining, pump impeller, gm liner, fitting, pump assembly, outer spherical bearings, and so on.

Bronze bearing material selection and performance of the main material

1, ZCuSn6Zn6Pb3, ZCuSn5Zn5Pb5, can be used to make work under medium load and rotating speed of liner wearing parts, gear, worm gear, etc.

2. ZCuSn10P1 is a typical tin phosphor bronze with high hardness and wear resistance. It can be used to manufacture parts that are subjected to strong friction under heavy load, high speed, and high temperatures, such as connecting rod bushing, gear, and worm wheel.

3. ZCuAl9Mn2, ZCuAl9Fe4, aluminum bronze has high strength, high compactness, and stable chemical properties. Commonly used in the valve body, worm gear, nuts, pipe fittings, and so on.

4. ZCuZn25Al6Fe3Mn3 high strength aluminum brass, the highest strength among special brass. High strength, high hardness, high wear resistance, moderate elasticity, and good corrosion resistance.

5.ZCuSn10P1 has high hardness, excellent wear resistance, and is not easy to bite and die. It has good casting performance and cutting performance, and has good corrosion resistance in the atmosphere and freshwater. Can be used for high load (below 20Mpa) and high sliding speed (8m/s) of wear-resisting parts, such as connecting rod, bushing, bearing bush, gear, worm wheel, etc.

6.ZCuSn10Pb5 is corrosion-resistant, especially to dilute sulfuric acid, hydrochloric acid, and fatty acid. Structural materials, corrosion - and acid-resistant fittings, and crusher bushing, bearing bush.

7, ZCuPb10Sn10 lubrication, wear resistance, and corrosion resistance is good, suitable for use as a bimetal casting material. Bearing for vehicles, bimetallic bearing for internal combustion engine with peak load up to 100Mpa, piston pin sleeve, friction plate, etc.

8, ZCuPb15Sn8 in the absence of lubricants and water lubricant conditions, good sliding and self-lubrication performance, free cutting, poor casting performance, corrosion resistance to dilute sulfuric acid is good. Bearing with high surface pressure and side pressure can be used to manufacture copper cooling pipe of cold rolling mill, parts with shock resistance load up to 50Mpa, the bimetallic bearing of the internal combustion engine, mainly used for piston pin sleeve with maximum load up to 70Mpa and acid resistance accessories.

9, ZCuZn38Mn2Pb2 has good mechanical properties and corrosion resistance, good wear resistance, good cutting performance. General-purpose structural parts, ships, instruments, etc. used in the appearance of simple castings, such as sleeve, bushing, bearing, sliding block.
