Abstract：

2E12 aluminum alloy is a high strength alloy for aeronautical industry.The tensile property,cupping testing method and bending performance were carried out for 2E12 aluminum alloy sheet under T3 and annealing condition at room temperature.The results reveal that the tensile strength,yield strength and yield ratios of annealing are much lower than that of T3 condition,while the elongation is almost consistent under two conditions.The cupping testing IE value is 12% higher than that of T3 condition,and minimum bending radius decreases by 10%,implying that the formability performance under annealing condition is superior to that under T3 condition.
