Air conditioner foils and method for preparing same

The invention relates to foils with alloying component proportioning and a method for making the same, in particular to aluminum foils used for the production of a radiator of an air conditioner and a method for making the same, belonging to the aluminum product processing field. The invention aims to overcome the defects existing in the prior art and provide air conditioner foils which are made by elements of iron, manganese, silicon, titanium and aluminum with the optimized component proportioning through processes of cast-rolling, cold-rolling and annealing; the aluminum foils have the advantages of compact structure and excellent comprehensive performance, and particularly facilitate the reduction of thickness and lower manufacturing costs; moreover, the aluminum foils can realize that air conditioner fins are not broken when the fins undergo the high-speed punching, thereby meeting market requirements.
