Abstract

This specification covers plate, rolled bar, sheet, and strip of copper-tin alloy (phosphor bronze plate), copper-tin-lead alloy (leaded phosphor bronze), and copper-tin-lead-zinc alloy (bearing bronze). Copper alloys covered include UNS Nos. C51000, C51100, C51180, C51900, C52100, C52180, C52400, C53400, and C54400. Product shall be manufactured by hot or cold working, rolling, and annealing. Chemical composition of the materials shall conform to UNS designation of the material. Product shall conform to chemical analysis, tensile strength and Rockwell hardness tests specified in the specification. Chemical composition testing shall be performed for each element, namely, copper, iron, lead, phosphorus, tin, and zinc. Tension test shall be made so that the longitudinal axis of the specimen is parallel to direction of rolling.

1. Scope

1.1 This specification establishes copper-tin alloy (phosphor bronze), copper-tin-lead alloy (leaded phosphor bronze), and copper-tin-lead-zinc alloy (bearing bronze), plate, sheet, strip, and rolled bar. The phosphor bronzes commonly are used for deep drawing into bellows and stamping and forming into spring devices and into terminals and connectors for electrical apparatus because they combine high strength with high elongation. The leaded phosphor bronzes are used where strength, corrosion resistance, and machinability are required. The bearing bronze is used in bushings, bearings, and load-bearing thrust washers. The following alloys are covered:
