Abstract

PURPOSE: To form a milk-white anodic oxide film free from color shading and having a uniform color tone by adding a specified amount of Fe and Ca to an Al alloy.
CONSTITUTION: An Al alloy consisting of, by wt., 1W3, especially about 1.5% Fe, 0.0005W0.03, especially 0.003W0.01% Ca and the balance Al and impurities is prepared. This Al alloy forms a milk-white anodic oxide film free from color shading and having a uniform color tone.
