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.
