The invention discloses a method for anodizing aluminum pendants. The method is characterized in that: anodizing bath solution is used as a degreasing agent; a first rinsing step for alkaline degreasing is arranged between a degreasing rinsing step and an alkaline degreasing step. The method comprises the following process steps of: degreasing, performing degreasing rinsing, performing alkaline degreasing rinsing 1, performing alkaline degreasing, performing alkaline degreasing rinsing 2, performing bright dipping, performing bright dipping rinsing 1, performing bright dipping rinsing 2, anodizing, performing oxidation rinsing 1, performing oxidation rinsing 2, performing electrolytic coloring, performing coloring rinsing 1, performing coloring rinsing 2, performing coloring rinsing 3, performing coloring rinsing 4, performing electrophoresis, performing electrophoresis rinsing 1, performing electrophoresis rinsing 2, sealing, performing sealing rinsing, air-drying and curing to obtain anodized electrolytic colored electrophoresis aluminum pendants, anodized electrolytic colored aluminum pendants, anodized electrophoresis aluminum pendants or the anodized aluminum pendants. By themethod, the problem that the process parameters of alkaline degreasing baths are greatly fluctuated due to the influence of the particularity of an alkaline degreasing process is solved, and the influence of the aluminum incensement of anodizing baths on the oxidation quality of the aluminum pendants is thoroughly prevented, degreasing and alkaline degreasing cost is reduced, and the quality of products is ensured.
