Description:

Aluminum bronzes are used for their combination of high strength, excellent corrosion and wear resistance. Aluminum bronze alloys typically contain 9-12% aluminum and up to 6% iron and nickel. Alloys in these composition limits are hardened by a combination of solid solution strengthening, cold work, and precipitation of an iron rich phase.They are also used in applications such as heavy duty sleeve bearings, and machine tool ways. They are designated by UNS C60800 through C64210. Aluminum bronze castings have exceptional corrosion resistance, high strength, toughness and wear resistance and good casting and welding characteristics. Aluminum bronze castings are designated as UNS C95200 to C95900.
