摘要： An aluminum alloy product for manufacturing structural components, made from direct chill casting ingots comprises, based on wt %: Zn 7.5˜8.7, Mg 1.1˜2.3, Cu 0.5˜1.9, Zr 0.03˜0.20, the balance being Al, incidental elements and impurities. The levels of Zn, Mg, Cu, and Zr in the aluminum alloy products satisfy the expressions of (a) 10.5≤Zn+Mg+Cu≤11.0; (b) 5.3≤(Zn/Mg)+Cu≤6.0; and (c) (0.24−D/4800)≤Zr≤(0.24−D/5000). D is the minimum length of a line section connecting any two points on the periphery of the cross section of the ingot and passing through the geometrical center of the cross section. 250 mm≤D≤1000 mm. The aluminum alloy products have a superior combination of strength and damage tolerance, and exhibit homogeneous and consistent performance on the surface, at various depths under the surface, and in the core of the product. A method of producing the aluminum alloy products is also provided.
