(0.457 mm).5.2.2 The product shall be manufactured by such hot-working, cold-working, and annealing processes as to producea uniform wrought structure in the finished product.5.2.2.1 The product shall be hot- or
13、cold-worked to thefinished size, and subsequently annealed, when required, tomeet the temper properties specified.1This specification is under the jurisdiction of ASTM Committee B05 on Copperand Copper Alloys and is the direct responsibility of Subcommittee B05.01 on Plate,Sheet, and Strip.Current e
