25、r cold worked to the finished size and subsequently annealed, when required, to meet the temperproperties specified.6. Chemical Composition6.1 The material shall conform to the chemical composition requirements in Table 1 for the copper or copper alloy UNS No.designation specified in the ordering in
26、formation.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 analysis required for unnamed elements.6.2 For alloys in which either copper or zinc is listed as “remainder,” copper or zinc
27、 is the difference between the sum of resultsof all elements determined and 100 %.
