6022 aluminum coil is a heat-treatable aluminum alloy in the Al-Mg-Si (6xxx) series, widely used for automotive body panels. It is known for its excellent formability in the T4 temper and its strong paint-bake hardening response, which allows the material to achieve higher strength after the painting process. This makes 6022 aluminum sheet especially suitable for lightweight automotive exterior and interior panels.
