What people usually call aluminum bronze rod is actually a copper-based alloy with aluminum as the main alloying element. It is an aluminum bronze plate containing iron and manganese elements. It belongs to high-strength heat-resistant bronze, and its aluminum content is generally not It will exceed 11.5%. Sometimes an appropriate amount of iron, nickel, manganese and other elements are added to further improve performance.
Aluminum bronze rods can be strengthened by heat treatment. Its strength is higher than that of tin bronze, and its high temperature oxidation resistance is also better. In addition, it has higher strength and good wear resistance. It is used for screws, nuts and copper rods with relatively high strength. Sleeves, sealing rings, etc., and wear-resistant parts, the most prominent feature is its good wear resistance.
Because the aluminum bronze rod containing iron and manganese 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 is very good, machinability is acceptable, it can be welded and not easy to braze, and the pressure processing is good in the hot state. Our country has been able to achieve mass production.
Compared with other metal materials in the industry, aluminum bronze rods have many excellent properties, such as high strength, hardness, and wear resistance. They are often used to manufacture gear blanks, threads and other parts. They also have good corrosion resistance. Therefore, it can be used to make corrosion-resistant parts, such as propellers, valves, etc., the material will not generate sparks under impact, and can be used to make non-sparking tool materials. It also has excellent thermal conductivity and stable rigidity. It is used as a mold material When stretching and rolling stainless steel plate heat exchangers, it will not produce mucous membranes or scratch workpieces, and has become a new type of mold material.
