The invention relates to the field of aluminum metallurgy and can be used to produce ingots from high quality aluminum alloys when manufacturing aerospace and automotive products. The use of this invention relates to the technology of secondary modification. The method of casting products from aluminum alloys includes the following stages: a) aluminum melt preparation in the alloying furnace; b) addition alloy introduction into melt; c) degassing of the aluminum melt containing the addition alloy; d) addition alloy re-introduction; e) filtration of the aluminum melt obtained at stage d) and f) feeding the filtered melt into the crystallizer. It ensures the improved effectiveness of the aluminum melt modification with addition alloys without additional constructional changes in existing lines for aluminum ingot casting. It allows reducing the alloy modification costs, decreasing the grain in resulting alloys and improving plastic and mechanical properties of the obtained cast ingots and their products.
