Title
(EN) ALUMINUM ALLOY SHEET AND ALUMINUM ALLOY SHEET MANUFACTURING METHOD
(ZH) 铝合金板和铝合金板的制造方法
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%, the ratio (B/A) of an endothermic peak in the 150-230 DEG C temperature range with a height A of 3-10 [mu]W/mg to an exothermic peak in the 230 DEG C to less than 330 DEG C temperature range with a height B of 20-50 [mu]W/mg isin a specified range.
(ZH) 在Mg和Si的合计含量高于1.2%的特定的组成的Al-Mg-Si系铝合金板的差示扫描量热分析曲线中,150~230℃的温度范围内,高度A为3~10μW/mg的吸热峰,与230℃以上且低于330℃的温度范围内,高度B为20~50μW/mg的放热峰的比(B/A)为特定的范围。
