24、ssing of castings into wrought products, it is not always practical to identify a specific castinganalysis with a specific quantity of finished material.6.2 Manufacture:6.2.1 The product shall be manufactured by such hot working, cold working, and annealing processes as to produce a uniformwrought s
25、tructure in the finished product.6.2.2 The product shall be hot or cold worked to the finished size, and subsequently annealed when required, to meet the temperproperties specified.7. Chemical Composition7.1 The material shall conform to the chemical composition requirements in Table 1 for the coppe
26、r alloy UNS Numbersspecified in the ordering information.7.1.1 Results of analysis on a product (check) sample shall conform to the composition requirements within the permittedanalytical variance specified in Table 1.7.2 These composition limits do not preclude the presence of other elements. By ag
27、reement between the manufacturer andpurchaser, limits may be established and analysis required for unnamed elements.B967/B967M 1827.3 For alloys in which zinc is listed as “remainder,” either copper or zinc may be taken as the difference between the sum ofresults of all elements determined and 100 %
28、. When all elements in Table 1 are determined, the sum of results shall be 99.5 %min.7.4 For alloys in which copper is listed as “remainder,” copper is the difference between the sum of results of all elementsdetermined and 100 %. When all elements in Table 1 are determined, the sum of results shall
29、 be 99.5 % min.7.5 All chemical composition requirements must be in accordance with the UNS Registered Composition or anotherinternationally recognized system for alloy designation (“other designation”). It is permissible for applications to have tighter(more restrictive) limits, but they must be co
30、mpletely within the registered UNS (or other designation) Composition. Whendifferent limits outside the registered limits are desired, a new Registered UNS Composition must be obtained.NOTE 2Refer to E527 Standard Practice for Numbering Metals and Alloys in the Unified Numbering System (UNS) for inf
