ASTM B103/B103M-19

Standard Specification for Phosphor Bronze Plate, Sheet, Strip, and Rolled Bar

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.
SCOPE
1.1 This specification establishes the requirements for 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:

1.2 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, SI units are shown in brackets. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined.  
1.3 The following safety hazard caveat pertains only to the test method(s) described in this specification.  
1.3.1 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
