ABSTRACT:
A method for making a polymer laminated drag cast aluminum alloy container stock material includes, in a preferred embodiment, drag casting an aluminum alloy suitable for forming into beverage containers into a sheet. The sheet is then cold rolled, at least one of the sheet's surfaces is cleaned and pretreated and a polymer material is laminated thereto. The polymer laminate on the drag cast aluminum alloy surface permits the use of drag cast aluminum alloy sheet material to be utilized, for example, as aluminum beverage container stock material.
