Abstract
A process for electrolytically treating aluminum or its alloys in the form of a strip, wire or foil material in a continuous manner which comprises continuously passing the material through an anodic oxidation treatment cell through which a direct current, alternating current or AC-superimposed direct current is caused to flow and an electrolytic coloring cell through which an alternating current or AC-superimposed direct current is caused to flow and carrying out electrolysis in both said cells to anodize and color the material in a continuous manner.
