Aluminum bronze generally contains no more than 11.5% aluminum, and sometimes an appropriate amount of iron, nickel, manganese and other elements are added to further improve the performance. Aluminum bronze can be heat-treated and strengthened,
Its strength is higher than that of tin bronze, and its resistance to high-temperature oxidation is also good. It has high strength and good wear resistance. It is used for screws, nuts, copper sleeves, sealing rings, etc. with relatively high strength, and wear-resistant parts. The most prominent feature is its good wear resistance. Aluminum bronze containing iron and manganese elements has high strength and wear resistance. After quenching and tempering, the hardness can be improved.
It has good high-temperature corrosion resistance and oxidation resistance. It has good corrosion resistance in the atmosphere, fresh water and seawater, and its machinability is acceptable. It can be welded but not easily brazed.

It has good high-temperature corrosion resistance and oxidation resistance. It has good corrosion resistance in the atmosphere, fresh water and seawater. It has good machinability and can be welded but not easily brazed. It is good for pressure processing under hot conditions. Because of the difference in aluminum content, special aluminum bronze has higher strength than alloy steel and hardness close to that of alloy steel. It is widely used in force structures, transmission parts, etc. In addition, due to its good corrosion resistance, pressure resistance and wear resistance, it is also used for transmission shaft gears of high-speed trains.
