The aluminum bronze containing iron and manganese has high strength and wear resistance. 2.1. High strength and outstanding wear resistance Used for high-strength screws, nuts, copper sleeves, sealing rings, etc. It has good high temperature corrosion resistance and oxidation resistance. It can increase the hardness after quenching and tempering. It is resistant to air, fresh water and sea water. Aluminum bronze can be strengthened copper strip for transmission by heat treatment, its strength is higher than tin bronze, and its high temperature oxidation resistance is also better., and wear-resistant parts. The aluminum content of aluminum bronze generally does not exceed 11.5%, and sometimes an appropriate amount of iron, nickel, manganese and other elements are added to further improve the function. The most outstanding feature is its outstanding wear resistance.. 3. It has good corrosion resistance, fair machinability, can be welded and is not easy to be welded, and is excellent in pressure production under hot conditionsThe structure of white copper is characterized by good mechanical function and corrosion resistance, and beautiful color. This free-cutting brass is often used as wall clock parts. It is used to cast high-load gears, shaft sleeves, and marine propellers. Brass alloys with a zinc content of 3642% are composed of solid solution and the most commonly used among them is the six-four brass with a zinc content of 40%. Tin can improve the strength of brass and its corrosion resistance to seawater, so it is called sailor brass, which is used for ship thermal equipment and propellers. Lead bronze is a bearing material widely used in modern engines and grinders. Manganese copper, constantan, and kaotong are manganese-nickel alloys with different manganese content. It has excellent electrical conductivity, thermal conductivity, ductility and corrosion resistance.
