Abstract

This invention provides an Al or Al alloy having an anodic oxide film, wherein the anodic oxide film has sites different in hardness in its thickness direction, and the difference in hardness between the highest hardness site and the lowest hardness site is 5 or more in terms of Vickers hardness. Preferably, the hardness at the lowest hardness site in the Al or Al alloy is 300 or more in terms of Vickers hardness. Preferably, the content of Fe in the anodic oxide film in the Al or Al alloy is not more than 500 ppm. The Al or Al alloy has an anodic oxide film having excellent cracking resistance even in the case of high hardness.
