摘要： Application of surface marking to metal stock, such as aluminum sheet, prior to or during scrap-generating manufacturing operations, to provide a detectable mark on pieces of manufacturing scrap derived from the marked sheet and commingled with scrap of other aluminum alloy sheet, so that the scrap can be sorted and the marked alloy scrap pieces separated from scrap of other alloy sheet to which the marking was not applied. Different markings, providing detectably different marks, may be respectively applied to sheet of different compositions if scrap pieces of more than two different compositions or compositional families are to be sorted and separated from each other.
