Abstract:
    An aluminum-alloy article such as a fastener or rivet is prepared by providing an aluminum-alloy article precursor, and in one form is in its solution treated/annealed state. A curable organic coating material is also provided. The method includes applying the organic coating material to the aluminum-alloy article precursor, and precipitation heat-treating the coated aluminum article precursor to its final heat-treated state, thereby simultaneously curing the organic coating. If the aluminum alloy temper is of the naturally aging type, it is optionally lightly deformed prior to precipitation treatment aging.
