(Specification)Standard Specification for Phosphor Bronze Wire
Standard Specification for Phosphor Bronze Wire
ABSTRACT
This specification establishes the requirements for round, square, and flat phosphor bronze wires of UNS Alloy Nos. C51000, C52100, and C52400 for general and spring applications. The material for manufacture shall be a casting billet of such purity and soundness as to be suitable for processing by hot working, cold working, and annealing to produce a uniform wrought structure in the finished product. Tempers available under this specification are O61 (annealed), H01 (¼ hard), H02 (½ hard), H03 (¾ hard), H04 (hard), H06 (extra hard), H08 (spring), and H10 (extra spring). Products shall be tested and shall adhere to dimensional (mass, diameter, thickness, length, width, straightness, and edge contours), mechanical (tensile and bending strength, and elongation), and chemical composition requirements.
SCOPE
1.1 This specification establishes the requirements for round and flat (square and rectangular) phosphor bronze wire of UNS Alloy Nos. C51000, C52100, and C52400 for general and spring applications.
1.1.1 Rectangular and square wire of the three alloys are generally available in sizes up to a maximum of 0.188 in. [5 mm] thick and 1.250 in. [32 mm] wide.
1.1.2 Round wire from Copper Alloy UNS No. C51000 is generally available in sizes up to 0.500 in. [13 mm] in diameter.
1.2 Units—The values stated in either inch-pound units or in SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may 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.
1.3 Additional requirements for these products are established in Specification B250/B250M, see Section 3.
1.4 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.
Note 1: It is to be understood that this specification is general. Since the product is used for many applications where the requirements of the operations used are too particular to be specified by any of the ordinary mechanical tests, it is frequently advisable to submit samples or drawings to the manufacturer and secure an adjustment of temper to suit the actual application for which the product is intended.
Note 2: Product in rod, bar and shape form is produced to Specification B139/B139M.
1.5 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.

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.
