Aluminum alloys suitable for use as anode structures in electrochemical cs are disclosed. These alloys include iron levels higher than previously felt possible, due to the presence of controlled amounts of manganese, with possible additions of magnesium and controlled amounts of gallium.

Aluminum battery alloys

Aluminum-magnesium-manganese alloy cold rolled to produce armor plate with improved ballistic properties.

Aluminum armor plate system

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.

Aluminum-magnesium alloys sheet exhibiting improved properties for

Improved alloy compositions for making sheet products, and related method aspects, based on adding zinc to Al-Mg alloys in an amount effective to avoid Type A Luder lines when cold working such sheet in annealed condition.
