WebAug 29, 2024 · Examples of substitutional alloys include bronze and brass, in which some of the copper atoms are substituted with either tin or zinc atoms. Figure \(\PageIndex{1}\): … Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different colours and mechanical, electrical, and chemical properties, but copper typically has the larger proportion. In use since prehistoric times, it is a substitutional alloy: atoms of the two constituents may replace … See more Brass is more malleable than bronze or zinc. The relatively low melting point of brass (900 to 940 °C, 1,650 to 1,720 °F, depending on composition) and its flow characteristics make it a relatively easy material to See more The high malleability and workability, relatively good resistance to corrosion, and traditionally attributed acoustic properties of brass, have made it the usual metal of choice for … See more Brass is susceptible to stress corrosion cracking, especially from ammonia or substances containing or releasing ammonia. The … See more Although forms of brass have been in use since prehistory, its true nature as a copper-zinc alloy was not understood until the post-medieval … See more To enhance the machinability of brass, lead is often added in concentrations of about 2%.
