Wrought Materials - High Copper Alloys

(1972 Edition)

Common names: Silicon Bronze

High-Silicon Bronze A

Silicon-Manganese Bronze

A copper alloy containing silicon and manganese, and with an alpha phase structure. The material has good hot- and cold-working properties, relatively high strength at ordinary and elevated temperatures, good corrosion resistance in a wide variety of chemical environments and is readily weldable. It is used in chemical, mechanical and marine engineering, where advantage can be taken of this desirable combination of properties, and also for decorative applications. The most commonly used wrought forms are plate, sheet, strip, rod, wire, tube and forgings.
