ABSTRACT:
A process for fabricating an aluminum alloy rolled sheet particularly suitable for use for an automotive body, the process comprising: (a) providing a body of an alloy comprising: about 0.8 to about 1.5 wt. % silicon, about 0.15 to about 0.65 wt. % magnesium, about 0.00 to about 0.1 wt. % copper, about 0.01 to about 0.1 wt. % manganese, about 0.05 to about 0.3 wt. % iron; and the balance being substantially aluminum and incidental elements and impurities; (b) working the body to produce a the sheet; (c) solution heat treating the sheet; and (d) rapidly quenching the sheet. In a preferred embodiment, the solution heat treat is preformed at a temperature greater than 460.degree. C. and the sheet is quenched by a water spray. The resulting sheet has an improved combination of formability, strength and corrosion resistance.
