ABSTRACT:
An aluminum-alloy tab stock, useful for non-detachable tabs having high yield strength and high bending endurance, and a process for manufacture thereof from a heat treatable core aluminum alloy and a non-heat treatable cladding aluminum alloy by arranging the alloys as layers of a composite, bonding the layers by hot-rolling the composite to a thickness reduction of 75-90%, cold-rolling the thinned composite to an additional thickness reduction of 60-70% to form the tab stock, solution heat treating the tab stock and rapidly cooling the tab stock. Optionally, aging to a selected temper may additionally be used.
