    OverviewAluminiumHistoryOther widely used specificationsOther metalsDyeingSealingCleaning

    Aluminium alloys are anodized to increase corrosion resistance and to allow dyeing (colouring), improved lubrication, or improved adhesion. However, anodizing does not increase the strength of the aluminium object. The anodic layer is insulative. When exposed to air at room temperature, or any other gas containing oxygen, pure aluminium self-passivates by forming a surface layer of amorphous aluminum oxide 2 to 3 nmthick, which provides very
