Abstract

The invention discloses a high-toughness casting aluminum alloy containing the following components in percentage by weight: 9.5-11.0 percent of Mg, 0.1-0.4 percent of Ti, 0.1-0.3 percent of RE, 0.15-0.30 percent of Si and the balance of Al and unavoidable trace impurities, wherein the content of single elements in the trace impurities is less than 0.10 percent, and the total content of the trace impurities is less than 0.50 percent. The invention also discloses a preparation method of the high-toughness casting aluminum alloy. The high-toughness casting aluminum alloy has the advantages of high tensile strength, high elongation, low price of raw materials, short production flow, easy control on the process flow and the like, and complicated smelting equipment and subsequent thermal treatment hot standby are not needed; on the premise of satisfying the mechanical properties of the members, the overall production cost is lower.
