# Characteristics of aluminum bronze copper sleeve

Characteristics of aluminum bronze copper sleeve
Aluminum bronze is a copper alloy in which the bronze contains no more than 11.5% aluminum. Sometimes, appropriate iron, nickel, manganese and other elements are added to further improve the performance. Aluminum bronze copper sleeve can be strengthened by heat treatment, its strength is higher than that of tin bronze copper sleeve, and its resistance to high temperature oxidation is better.

The aluminum bronze copper sleeve containing iron and manganese elements has high strength and wear resistance, and its hardness can be improved after quenching and tempering, and it has good corrosion resistance and oxidation resistance at high temperature. It has good corrosion resistance in atmosphere, fresh water and sea water, machinability is fair, welding ability is not easy to fiber welding, and good pressure machining under hot state.

Aluminum bronze has good cutting and grinding properties, can be welded, and is easy to be formed by hot machining. Alloy is mainly used in the manufacture of bracket, gear, bushing, bushing, nozzle, flange, rocker arm, pilot valve, pump rod, CAM, fixed nut and other high strength and wear resistant structural parts. With high strength and wear resistance, widely used in high voltage electrical appliances, shipbuilding industry, after quenching and tempering treatment can further improve the strength, wear resistance and oxygen resistance.

Zcual10-3-2 properties and application range: high mechanical properties and wear resistance, heat treatment, high temperature corrosion resistance and oxidation resistance. 10-3-2 Good corrosion resistance in atmosphere, fresh water and sea water, can be welded, not easy to braze, large casting from 700℃ air cooling can prevent brittleness.

Zcual10-3, grade ZCuAl10Fe3, has high mechanical properties, good wear resistance and corrosion resistance, can be welded, not easy to braze, large castings from 700℃ air cooling can prevent brittle. It is suitable for heavy castings with high strength, wear resistance and corrosion resistance, such as copper sleeves, nuts, turbines, and pipe fittings working below 250℃.

Qal9-4 aluminum bronze; It is aluminum bronze containing iron. It HAS HIGH STRENGTH AND ANTI-FRICTION, GOOD CORROSION RESISTANCE, GOOD PRESSURE processing under HOT state, can be welded by electric and gas, but poor brazing, can be used as a substitute for high tin WEAR-resistant bronze. Aluminum-bronze 9-4 is used to make wear resistant and corrosion resistant parts working under high load, such as bearings, bushings, gears, worm wheels, valve seats, copper sliding plates, etc., and also used to make bimetallic wear resistant parts.

Qal9-4-2 aluminum bronze: has very high mechanical properties, excellent corrosion resistance in air, fresh water and sea water, high corrosion fatigue strength, good castability, good wear resistance, heat resistance below 400℃, heat treatment, good welding performance, not easy to braze.

Chemical composition of C86300 aluminum bronze
C86300 aluminum bronze is the United States label number, generally used in Rongchang self-lubricating bearing matrix above, its material composition:
cu:60-66
zn:22-28
al:4-7
fe:2-5
Mn:3-5
C86300 aluminum bronze hardness is relatively high, the bearing capacity is relatively good copper alloy, often used to make Rongchang graphite copper sleeve, or self-lubricating bearings. A copper alloy with high cost performance.

Qal9-2 aluminum bronze; It is aluminum bronze containing manganese. With high strength, in the atmosphere, fresh water and sea water corrosion resistance is very good, can be welding and gas welding, not easy to braze, in hot and cold state under the pressure of good processing. For high strength corrosion-resistant parts and pipe fittings and sea-going parts working in steam media below 250℃.
