Aluminum bronze sleeve (CuZn25Al5Mn4Fe3-C)

Characteristics of Aluminum Bronze
 A copper-based alloy with aluminum as the main alloying element is an aluminum bronze containing iron and manganese elements. It is a high-strength heat-resistant blue and sometimes an appropriate amount of iron, nickel, manganese and other elements are added to further improve its 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. It has high strength and good wear resistance. It is used for high-strength screws, nuts, copper sleeves, sealing rings, etc., The most prominent feature is its good wear resistance. Aluminum bronze containing iron and manganese elements has high strength and wear resistance. It can increase the hardness after quenching and tempering. It has good high temperature corrosion resistance and oxidation resistance. It has good corrosion resistance in the atmosphere, fresh water and sea water. Good machinability, can be welded and not easy to braze, good pressure processing in hot state. Aluminum bronze has many excellent properties. Aluminum bronze has high strength, hardness and wear resistance, and is often used to make gear blanks, threads and other parts. Aluminum bronze has good corrosion resistance, so it can be used to manufacture corrosion-resistant parts such as propellers and valves. Aluminum bronze does not produce sparks under impact, and can be used to make non-sparking tool materials. It has excellent thermal conductivity and stable rigidity. As a mold material, it has the advantages of not sticking to the mold and scratching the workpiece when stretching and calendering the stainless steel plate heat exchanger. It has become a new type of mold material.
