Aluminum Bronze Casting

Copper aluminum alloys are commonly called aluminum bronzes. They contain 89-95% copper, small quantities of aluminum and in some cases there will be iron, nickel, manganese or silicon. Aluminum bronze casting is used for applications demanding high strengths and corrosion resistance. Aluminum bronzes form two distinct groups of copper aluminum alloys, AB1 and AB2, with iron, nickel and manganese as the component metals. Brass is another group of copper alloys.

Probably bronze casting was the first form of metal casting. That deduction is suggested by the discovery of bronze statues and sculptures from various parts of the world. Today we use aluminum bronze casting for a variety of applications, because of its retaining ductility and strength at elevated temperatures and adverse conditions. The corrosion resistance depends on the casting process and the heat treatment it got. Continue...
