Estimating the term…
Aluminum alloys, metal products made using aluminum alloys, and methods of processing the aluminum alloys are disclosed. The disclosed alloys can be prepared using large amounts of recycled content, such as up to 100% recycled content. The disclosed aluminum alloys include amounts of iron and manganese in excess of comparable aluminum alloys commonly made by alloying prime aluminum. For example, the disclosed aluminum alloys can include a ratio of a total amount of Mn and Cr to an amount of Fe that is greater than 0.6. The disclosed aluminum alloys can be produced by casting a 6xxx aluminum alloy to generate a cast product, which can be subsequently processed to generate rolled products.
An aluminum alloy, comprising Al, Mn, Cr, and Fe, wherein a ratio of a total amount of Mn and Cr to an amount of Fe is greater than 0.6, and wherein at least a portion of the aluminum alloy comprises recycled aluminum content.
