Mechanical properties and uses

The aluminum bronze rod has good cutting and grinding performance, can be welded, and is easy to be formed by hot processing. Aluminum bronze rod alloy is mainly used to manufacture high-strength and wear-resistant structural parts such as brackets, gears, shaft sleeves, bushings, nozzles, flanges, rocker arms, pilot valves, pump rods, cams, and fixing nuts.
Aluminum bronze generally does not contain more than 11.5% of aluminum, and sometimes an appropriate amount of iron, nickel, manganese and other elements are added to further improve performance. Aluminum bronze can be strengthened by heat treatment, its strength is higher than tin bronze, and its high temperature oxidation resistance is also better.

Because aluminum bronze containing iron and manganese elements has high strength and wear resistance, it can increase the hardness after quenching and tempering, and has good high temperature corrosion resistance and oxidation resistance. Corrosion resistance in the atmosphere, fresh water and sea water Very good, machinability is acceptable, welding is not easy to weld, and the pressure processing is good in hot state.
