Heat Treating of Bronzes

Bronzes generally are used to describe many different copper-base alloys in which the major alloying addition is neither zinc nor nickel. They are generally classified by their major alloying elements, for example, tin bronzes with phosphorus used as a deoxidizer, aluminum bronzes, nickel-aluminum bronzes, silicon bronzes, and beryllium bronzes. This article briefly discusses the types, hardening mechanisms, heat treatment processes, applications, and mechanical properties of these bronzes and high-copper alloys.
