Anodic oxidation is usually performed in electrolyte solutions such as sulfuric acid, oxalic acid, or chromic acid. Aluminum is used as the anode, lead and other metals as the cathode. Under the action of direct current electric field, anion (OH) moves to the anode, and new oxygen is generated in the anode and aluminum as the anode ACTS as an oxidation film. In the electrolyte, the acid can partially dissolve the oxidation film and produce pores, so that the oxidation reaction can develop in depth. This method enables the surface of aluminum to form a porous structure, can carry out various coloring treatment, and can be used as the paint substrate.Please notice our perfect aluminium tube case .
