An aluminum alloy hard foil for battery collector comprises the following components: 0.8-1.5wt% of Mn; 0.05-0.20wt% of Cu; 0.3-0.7wt% of Fe, and the balance of Al and inevitable impurity. The thickness of the alminium alloy hard foil for battery collector is 9-20 mu m. More than thirty subgrains are provided in a thickness direction. The tensile strength is 280-350MPa and the extensibility is more than 3.5%. According to the composition, the aluminum alloy hard foil for battery collector has a high strength and excellent extensibility. |
