Control method of iron-rich aluminum alloy structure

The invention belongs to the technical field of metal material processing engineering, and particularly relates to a control method for an iron-rich aluminum alloy structure. The structure control of the iron-rich aluminum alloy is realized by controlling the components of a plate blank (comprising 1.10-1.80% of Fe, 0.10-0.15% of Si, less than or equal to 0.05% of Cu, less than or equal to 0.05% of Mn, less than or equal to 0.05% of Ti, less than or equal to 0.005% of Mg, less than or equal to 0.005% of Zn and the balance of Al and impurities), casting and rolling a grain structure (the grain size is I-II level), performing a cold rolling and foil rolling process, homogenizing and annealing, controlling the grain size to be 15-30 [mu] m and the second phase to be 0.2-0.5 [mu]m . According to the invention, not only are the problems of mechanical property, surface quality and thinner foil rolling of the iron-rich aluminum foil well solved, but also the mechanical property and the forming property are organical
