Abstract
An aluminum plating material to be anodized comprising a substrate, a metal layer formed on the substrate, the metal layer being electrochemically nobler than aluminum and an aluminum alloy, and an aluminum layer formed on the metal layer. The aluminum plating material prevents peeling of an aluminum layer from the substrate upon anodizing, which allows formation of uniform pores of the anodizing film, and which provides good coloring and anitiwear properties of the anodized film.
