3、tablishes the requirements for copper-tin alloy (phosphor bronze), copper-tin-lead alloy (leadedphosphor bronze), and copper-tin-lead-zinc alloy (bearing bronze), plate, sheet, strip, and rolled bar. The phosphor bronzescommonly are used for deep drawing into bellows and stamping and forming into sp
4、ring devices and into terminals and connectorsfor electrical apparatus because they combine high strength with high elongation. The leaded phosphor bronzes are used wherestrength, corrosion resistance, and machinability are required. The bearing bronze is used in bushings, bearings, and load-bearing
