1、Designation: B 159/B 159M 05Standard Specification forPhosphor Bronze Wire1This standard is issued under the fixed designation B 159/B 159M; the number immediately following the designation indicates the yearof original adoption or, in the case of revision, the year of last revision. A number in par
2、entheses indicates the year of last reapproval.A superscript epsilon (e) 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 the requirements forround, square
3、and flat phosphor bronze wire of UNS AlloyNos. C51000, C52100, and C52400 for general and springapplications.1.1.1 Rectangular and square wire of the three alloys aregenerally available in sizes up to a maximum of 0.188 in. 5mm thick and 1.250 in. 32 mm wide.1.1.2 Round wire from Copper Alloy UNS No
4、. C51000 isgenerally available in sizes up to 0.500 in. 13 mm indiameter.1.2 The values stated in either inch-pound units or in SIunits are to be regarded separately as standard. Within the text,the SI units are shown in brackets. The values stated in eachsystem are not exact equivalents; therefore,
5、 each system shallbe used independently of the other. Combining values from thetwo systems may result in nonconformance with the specifi-cation.1.3 Additional requirements for these products are estab-lished in Specification B 250/B 250M, see Section 3.1.4 This standard does not purport to address a
6、ll of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.NOTE 1It is to be understood that this specification is genera
7、l. Sincethe product is used for many applications where the requirements of theoperations used are too particular to be specified by any of the ordinarymechanical tests, it is frequently advisable to submit samples or drawingsto the manufacturer and secure an adjustment of temper to suit the actuala
