6022 Alloy Sheet
6022 is a heat treatable low copper, Al-Si-Mg sheet alloy developed by Alcoa to satisfy the needs of automotive manufacturers for closure panels, such as a hood, decklid or a door. This alloy was developed to provide improved corrosion resistance, higher formability and greater strength for dent resistance after thermal exposure (paint bake) compared to other competitive offerings. It can satisfy the forming and strength requirements for both exterior body panel as well as structural applications. It can be provided as a coil or as blanks in tempers T4, T43 and T4E32.
Alloy 6022 is being considered in many new body closure panels programs by the global automotive community to take advantage of these superior performance attributes.
