Abstract: A method is disclosed, which includes the step of preparing an aluminum alloy body for solutionizing. The aluminum alloy body may include not greater than 0.06 wt. % Fe, where at least some Fe is present. The aluminum body may include not greater than 5.0 wt. % Mg. The balance of the aluminum alloy body may be aluminum and unavoidable impurities. The aluminum alloy body may include a first vol. % of Fe-bearing particles. The method may include solutionizing the as-prepared aluminum alloy body. The solutionizing step may include dissolving at least some of the Fe-bearing particles into solid solution, thereby decreasing the first vol. % of Fe-bearing particles to a second vol. % of Fe-bearing particles in the as-solutionized aluminum alloy body.

Abstract: New aluminum alloy compositions are provided. The new aluminum alloy compositions may include, for instance, from 20 to 600 ppm Fe and from 10 to 800 ppm Mn. A ratio of Fe (ppm)-to-Mn (ppm) in the aluminum alloy may be from 0.25:1 to 7:1. The new aluminum alloys may be useful, for instance, as an electrode alloy product.
