The following alloys are covered:.

Referenced Documents purchase separately The documents listed below are referenced within the subject asfm but are not provided as part of the standard. 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.

Phosphor Bronze

All of the above alloys contain small amounts of phosphorus, used as a deoxidant in melting, and to enhance the mechanical properties. The b03 stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other.


ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Within the text, SI units are shown in brackets. Product shall be manufactured by hot or cold working, rolling, and annealing.

Combining values from the two systems may result in non-conformance with the standard. Historical Version s – view previous versions of standard. Asmt 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.

A1 C 96 4. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. Product shall asstm to chemical analysis, tensile strength and Rockwell hardness tests specified in the specification.


The following alloys are covered: C A 92 8. This specification covers plate, adtm bar, sheet, and strip of copper-tin alloy phosphor bronze platecopper-tin-lead alloy leaded phosphor bronzeand copper-tin-lead-zinc alloy bearing bronze.

Copper alloys covered include UNS Nos. Link to Active This link will always route to the current Active version of the standard.

The bearing bronze is used in bushings, bearings, and load-bearing thrust washers.

The leaded phosphor bronzes are used where strength, corrosion resistance, and machinability are required. This abstract is a brief summary of the referenced standard. Chemical composition of the materials shall conform to UNS designation of the material.
