1、Designation: B 140/B 140M 07Standard Specification forCopper-Zinc-Lead (Red Brass or Hardware Bronze) Rod,Bar, and Shapes1This standard is issued under the fixed designation B 140/B 140M; the number immediately following the designation indicates the yearof original adoption or, in the case of revis
2、ion, the year of last revision. A number in parentheses 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
3、 establishes the requirements forcopper-zinc-lead (leaded red brass or hardware bronze) rod,bar, and shapes of UNS Alloy Nos. C31400, C31600, andC32000 available for screw machine applications.1.2 UnitsThe values stated in inch-pound units or SI unitsare to be regarded separately as standard. Within
4、 the text, SIunits are shown in brackets. The values in each system are notexact equivalents; therefore, each system shall be used inde-pendently of the other. Combining values from the two systemsmay result in nonconformance with the specification.2. Referenced Documents2.1 ASTM Standards:2B 249/B

Material and Manufacture5.1 Material:5.1.1 The material of manufacture shall be a form (castbillets, logs, or rods) of Copper Alloy UNS Nos. C31400,C31600, or C3
15、2000 of such purity and soundness as to besuitable for processing into the products prescribed herein.5.2 Manufacture:5.2.1 The product shall be manufactured by such hot work-ing, cold working, straightening, and annealing processes as toproduce a uniform wrought structure in the finished product.6.
16、 Chemical Composition6.1 The material shall conform to the chemical compositionrequirements in Table 1 for the Copper Alloy UNS No.designation specified in the ordering information.6.1.1 These composition limits do not preclude the presenceof other elements. By agreement between the manufacturer and
17、the purchaser, limits may be established and analysis requiredfor unnamed elements.6.2 For alloys in which zinc is listed as the “remainder,”either copper or zinc may be taken as the difference betweenthe sum of results of all other elements determined and 100 %.When copper is so determined, that di
18、fference value shallconform to the requirements given in Table 1.6.3 When all elements in Table 1 are determined, the sum ofthe results shall be 99.6 % minimum.7. Temper7.1 Tempers, as defined in Classification B 601, available tothis specification are O60 (soft anneal), H02 (half-hard), andH04 (har
