Materials and Manufacture7.1 MaterialThe ma

22、terial of manufacture shall be a castbar, slab, cake, billet, or other form of the composition given inTable 1 for the specified alloy, suitable for processing into theproduct prescribed in this specification.7.2 ManufactureThe product shall be produced by eitherhot- or cold-working operation. It sh

23、all be finished, unlessotherwise specified, by such hot working, cold working,annealing, or heat treatment as may be necessary to meet theproperties specified in Table 2.7.3 EdgesThe edges shall be slit or rolled edges asspecified by the buyer. Slit edges shall be furnished unlessotherwise specified

24、 or agreed upon between the purchaser andsupplier or manufacturer.8. Chemical Composition8.1 The materials shall conform to the chemical composi-tional requirements in Table 1 for the corresponding CopperAlloy UNS Number designation specified in the orderinginformation.8.2 These composition limits d

25、o not preclude the presenceof other elements. Limits for unnamed elements may beestablished and analysis required by agreement between manu-facturer or supplier and purchaser when required.8.3 Copper, when given as the remainder, is determined asthe difference between the sum of results for all elem
