http://che.uri.edu/course/che333/Structure 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%. Since lead has a lower melting point than the other constituents of the brass, it tends to … See more Dezincification-resistant (DZR or DR) brasses, sometimes referred to as CR (corrosion resistant) brasses, are used where there is a large corrosion risk and where normal brasses do not meet the requirements. Applications with high water temperatures, See more The bactericidal properties of brass have been observed for centuries, particularly in marine environments where it prevents biofouling. Depending upon the type and concentration of pathogens and the medium they are in, brass kills these microorganisms within … See more
WebSelect all that apply. When a substitutional atom is introduced into a crystal structure comprised of atoms with smaller radius, the solute induces tensile stresses in the surrounding lattice.
