ABSTRACT:
A modified type 3004 aluminum alloy is provided characterized by an improved combination of cold workability and physical properties having particular use in the deep drawing of containers, such as beverage cans, and the like, said alloy containing a relatively high level of manganese ranging by weight from about 1.6 to 3 percent. The improvement is particularly apparent in the production of chill cast shapes (sheet metal stock), such as by the continuous casting of the alloy between a pair of water-cooled rolls.
