PROBLEM TO BE SOLVED: To provide a 6000 series aluminum alloy sheet capable of exhibiting higher BH properties even in the case of being subjected to room temperature aging in which its strength before bake coating is made high.SOLUTION: In a specified 6000 series aluminum alloy sheet, the total content of Mg and Si present in a specified atomic cluster is controlled, the total content of Mg and Si present in the atomic cluster is secured upon balancing with the total content of Mg and Si made into solid solution in a matrix, and the BH properties after room temperature aging and the proof stress after BH treatment are further improved. |
