An aluminum alloy and anode oxidation method thereof. The aluminum alloy is formed of the following components, in percent by mass: 5.0%-5.4% of Zn, 0.9%-1.2% of Mg, < 0.05% of Cu, < 0.05% of Si, < 0.1% of Fe, < 0.05% of Mn, < 0.1% of Zr, < 0.05% of Ti, < 0.15% of other impurities, with the balance being Al. The anode oxidation method comprises the following sequentially performed steps: degreasing, first de-smutting, chemical polishing, second de-smutting, anode oxidation, sealing, and drying. In the aluminum alloy, influence of formation of relative flow mark of chemical combination is eliminated, and the strength thereof is enhanced. |
