Abstract
The aluminum alloy sheet of the present invention is a specific 6000-series aluminum alloy sheet in which the total sum (total amount) of Mg and Si existing in specific aggregates of atoms (clusters) is regulated and the total sum of Mg and Si existing in the aggregates of atoms is ensured so as to be balanced with the total amount of Mg and Si solid-solutionized in the matrix, and thus BH response (bake hardenability) after natural aging at room temperature and proof strength after BH treatment (bake hardening treatment) are further improved.
