Abstract
This disclosure provides an aging process or a method for aging aluminum alloys. For example, the aging process can be performed on 6xxx Al—Si—Mg—Cu aluminum alloys to result in production of such alloys with improved intergranular corrosion (IGC) resistance. The disclosed aging process includes subjecting a solution heat treated and quenched 6xxx aluminum alloy to a temperature above an aging hardening temperature of said alloy but below the solution heat treatment temperature for a short period of time, and then subjecting said alloy to an aging heat treatment at an aging hardening temperature.
