Abstract: Provided are an aluminum alloy for die casting that has excellent die-castability, a molding with high hardness, and a molded article with excellent sheen. The aluminum alloy for die casting includes 0.5 to 2.5 wt. % Mn, 0.2 to 1.0 wt. % Cr, 0.1 to 0.5 wt. % Ti, 0.1 to less than 0.5 wt. % Mg, and Al. The molding is obtained by die-casting the aluminum alloy for die casting. The molding obtained by die-casting the aluminum alloy has excellent die-castability and high hardness. By performing the alumite treatment on the surface of the molding, a molded article having excellent sheen is obtained.
