Abstract:
1. An aluminum alloy sheet as an Al—Mg—Si aluminum alloy sheet which comprises: 0.35 to 1.0 percent by mass of magnesium (Mg); 0.5 to 1.5 percent by mass of silicon (Si); 0.01 to 1.0 percent by mass of manganese (Mn); and 0.001 to 1.0 percent by mass of copper (Cu), with the remainder being aluminum (Al) and inevitable impurities, wherein the amount of dissolved silicon (Si) is 0.55 to 0.80 percent by mass, wherein the amount of dissolved magnesium (Mg) is 0.35 to 0.60 percent by mass, and wherein the ratio of the amount of dissolved silicon (Si) to the amount of dissolved magnesium (Mg) is 1.1 to 2.
