Abstract
(EN)

In a differential scanning calorimetric curve of an Al—Mg—Si aluminum alloy sheet with a specific composition in which the total content of Mg and Si is greater than 1.2%, a ratio (B/A) of an endothermic peak within the temperature range of 150-230° C. with a height A of 3-10 μW/mg to an exothermic peak within the temperature range of 230° C. or above and below 330° C. with a height B of 20-50 μW/mg is to be within a specified range.
