About Alloy
C86300, also known as manganese bronze, is a versatile copper alloy distinguished by its high strength, excellent corrosion resistance, and wear resistance. Composed primarily of copper, manganese, and zinc, with additional elements like iron and aluminum, C86300 exhibits superior mechanical properties suitable for various industrial applications. It is particularly valued in environments where friction, wear, and stress are prevalent, such as in heavy machinery components, gears, bushings, and bearings. C86300's robustness and machinability make it a preferred choice for applications requiring reliable performance under demanding conditions. Compliance with ASTM and other international standards ensures consistent quality and reliability in manufacturing and usage.
