Multi-alloy composite sheets and methods of producing the composite sheets for use in automotive applications are disclosed. The automotive application may include an automotive panel having a bi-layer or a tri-layer composite sheet with 3xxx and 6xxx aluminum alloys. The composite sheets may be produced by roll bonding or multi-alloy casting, among other techniques. Each of the composite sheets may demonstrate good flat hem rating and mechanical properties, long shelf life, and high dent resistance, among other properties. |
