Abstract
Surface-treated Al or Al alloy materials which excel in adhesive property, formability, weldability, phosphatability, paint adhesion, and post-painting corrosion resistance are provided by forming a coated layer containing Zn and Fe or one or more of Si oxides, Al oxides and Al hydroxides together therewith, on the surface of Al or Al alloy base. The surface-treated Al or Al alloy materials are useful as metallic material to be painted and used after press forming and other processing, spot or laser welding and phosphating, including panel materials for automobiles and other various vehicles, shells for housefold electrical apparatus, and building materials.
