Abstract

A method for producing a high tensile aluminum alloy for an auto heat exchanger, comprising: supplying molten aluminum alloy comprising: Si 0.3% to 1.2%, Fe 0.05% to 0.7%, Mn 0.8% to 2.0%, Zn 0.5% to 4.0%, and other part comprising aluminum and unavoidable impurity according to mass; processing the molten aluminum alloy into plates with thickness 2 to 12mm by continuous casting forging method; and curling the plates immediately; the temperature is 530 deg. C. or even lower of the aluminum alloy material to be curled; in addition, cooling the curled aluminum alloy material with an average cooling speed 15 deg. C / h or even higher, and then developing the aluminum alloy material; in addition, undergoing cold rolling at least two times and annealing at least two times so as to obtain finishedplates with a thickness no more than 0.1mm.
