Aluminum-magnesium alloys sheet exhibiting improved properties for forming and method aspects of producing such sheet

摘要

Described is Al-Mg Sheet, in annealed condition, which has good formability and is further characterized structurally by its ability to be formed in the manufacture of sheet-metal products without being marked by Type A Luder lines. Also described are method aspects of producing such sheet, including the steps of selectively annealing and quenching followed by stretching.
