ASTM B103/B103M-09

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:B103/B103M–07 Designation: B 103/B 103M – 09
Standard Specification for
1
Phosphor Bronze Plate, Sheet, Strip, and Rolled Bar
This standard is issued under the fixed designation B 103/B 103M; the number immediately following the designation indicates the year
of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval.
A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
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:

NOTE 1—All of the above alloys contain small amounts of phosphorus, used as a deoxidant in melting, and to enhance the mechanical properties.
1.2 The values stated in either inch-poundSI units or SIinch-pound units are to be regarded separately as standard. Within the
text, the SI units are shown in brackets. The values stated in each system aremay not be exact equivalents; therefore, each system
shall be used independently of the other. Combining values from the two systems may result in non-conformance with the
specification. standard.

The UNS system for copper and copper alloys (see Practice E 527) is a simple expansion of the former standard designation system accomplished by the addition of
a prefix “C” and a suffix “00.” The suffix can be used to accommodate composition variations of the base alloy.
