| description | The invention provides a high-strength corrosion-resistant aluminum alloy and a casting method thereof. By reasonably optimizing the content and proportion of Zn, Mg and Si elements in the aluminum alloy, properly increasing the content of Zn, Mg and Si and adding a proper amount of rare earth element Sc, rare earth element Ce and transition metal element Zr, the effects of refining crystal grains, obtaining good toughness and high strength and improving corrosion resistance are achieved, and the service life of the aluminum alloy is prolonged. Therefore, on the premise that the high strength of the aluminum alloy is guaranteed, the corrosion resistance is remarkably improved, and meanwhile the aluminum alloy further has good plasticity. According to the invention, the aluminum alloy material is prepared by adopting a specific formula and a spray forming process, the microscopic structure of the aluminum alloy material is obviously refined, and the precipitated phase is fine and uniformly distributed, so that |
