Abstract: Provided is a 6000-series aluminum alloy sheet having good formability for an automotive body panel, which can be manufactured without greatly varying an existing composition or an existing manufacturing condition. The amount of solute Si and the amount of solute Cu in an Al—Mg—Si aluminum alloy sheet are increased in a balanced manner, so that the sheet has a dislocation density within a specific range when tensile deformation in a low-strain region is applied to the sheet. This suppresses localization of dislocations introduced into a material due to tensile deformation during press forming into an automotive body panel, and allows dislocations to be evenly multiplied from the low-strain region to a high-strain region. Consequently, uneven deformation is suppressed during forming into the automotive body panel, and good work hardenability is exhibited.

Thus, the aluminum alloy sheet is allowed to have formability, corrosion resistance, and such high strength as to be demanded of structural components.
