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 C32000 of such purity and soundness as to besuitable for processing
18、 into the products prescribed herein.5.2 Manufacture:5.2.1 The product shall be manufactured by such hotworking, cold working, straightening, and annealing processesas to produce a uniform wrought structure in the finishedproduct.6. Chemical Composition6.1 The material shall conform to the chemical
19、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 andthe purchaser, limits may be established and analysis requiredfor un
