The invention provides a method for producing a black aluminum profile by using anodized single nickel salt for coloring. The method specifically comprises the steps of aluminum profile surface pre-treatment, aluminum profile surface anodizing, alternate-current electrolytic coloring, boiling water sealing and the like, and in the process of alternate-current electrolytic coloring, the aluminum profile is subjected to voltage control coloring at three stages. Meanwhile, the invention provides the black aluminum profile obtained according to the method. The method for producing the black aluminum profile by using the anodized single nickel salt for coloring is implemented under a normal-temperature environment, and energy consumption is low; a dense anode oxide film with high surface smoothness is obtained after anodizing is completed; and the continuous and stable pure black anodized aluminum profile is produced after three-stage coloring treatment is carried out, and is uniform and bright in surface, small in color difference, good in decoration effect, and well resistant to rust, salt water, salt spray, humidity, heat, cold and scratch.
