Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Anodizing is a “Conversion Coating”, and is very different than paints, plating and other common coatings on metal. While paints and plating sit on top of the surface of the aluminum, anodizing converts the outer layer of aluminum to aluminum oxide, so the coating is fully integrated with the aluminum substrate. Therefore, anodizing doesn’t chip or flake like paint, it is a completely integral with the underlying metal. The anodized aluminum process typically includes the following steps: cleaning, pre-treating, anodizing, coloring, and sealing.
