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.
