Materials and Manufacture5.1 Materials:5.1.1 The material of manufacture sh
25、all be a cast rod, bar, or billet of the designated copper or copper-alloy of such purity andsoundness to be suitable for processing into the products prescribed herein.5.1.2 In the event that heat identification or traceability is required, the purchaser shall specify the details desired.NOTE 2Due
26、to the discontinuous nature of the processing of castings into wrought products, it is not always practical to identify a specific castinganalysis with a specific quantity of finished material.5.2 Manufacture:5.2.1 The product shall be manufactured by such hot-working, cold-working, and annealing pr
27、ocesses as to produce a uniformwrought structure in the finished product.5.2.2 The product shall be hot- or cold-worked to the finished size and subsequently annealed, when required, to meet thetemper properties specified.6. Chemical Composition6.1 The material shall conform to the chemical composit
28、ion requirements in Table 1 for the copper or copper alloy UNS No.or EN 1412 No. designation specified in the ordering information.6.1.1 These composition limits do not preclude the presence of other elements. By agreement between the manufacturer and thepurchaser, limits may be established and anal
29、ysis required for unnamed elements.6.2 For alloys in which either copper or zinc is listed as “remainder,” copper or zinc is the difference between the sum of resultsof all elements determined and 100 %. When all elements in Table 1 for the specified copper-alloy are determined, the sum ofresults sh
