Patent abstract: This invention relates to a high-strength aluminum alloy and its preparation method. In the aluminum alloy, the mass percentage content of each alloying element is: Si 0.75～0.83％, Mg 0.98～1.05％, Cu 0.44～0.55％, Mn 0.60～0.66％, Cr 0.04～0.25％, Fe≤0.165, Ti≤0.15％, Zn≤0.30％, V≤0.015％, Zr≤0.02％. The remainder is Al and unavoidable impurities. The content of each impurity element does not exceed 0.05％, and the total amount of impurities does not exceed 0.15％. The preparation method includes steps such as alloy smelting, billet casting, homogenization heat treatment, extrusion molding, and aging treatment. The obtained aluminum alloy has a yield strength ≥350MPa, a tensile strength ≥390MPa, and an elongation rate ≥10％. It is particularly suitable for use in automotive anti-collision beams, with a lightweighting and weight-reduction effect that can reach more than 20％.
