The invention provides an aluminium hard foil for a battery collector, which has a strength of a certain degree and good stretching rate. The aluminium hard foil for a battery collector with low resistance has 0.2-0.7 mass% of Fe, 0.1-0.5mass% of Mn. Si is controlled to be under 0.2mass%, and the remain is A1 and inevitable impurities and the purity is over 99.0mass%. The thickness of the aluminium hard foil is 9-20Mum, the amount of subgrains in the thickness direction is over 30, and the tensile strength is over 200MPa and below 270MPa and the stretching rate is over 4.0%.
