Anodizing is an electrochemical process that converts a metal surface into a decorative, anodic oxide finish. The anodic oxide structure is made up of a layer of aluminium oxide on the surface of the aluminium which slightly increases the thickness of the metal.
The aluminium oxide fully integrated with the underlying aluminium profile, which protects aluminium from corrosion. It has a porous structure that allows for secondary processes such as colouring and sealing.
The anodizing process for aluminum not only enhances the appearance of aluminum but also improves its durability and corrosion resistance. The ability to dye the oxide layer opens up a wide range of possibilities for designers and manufacturers to achieve various aesthetic effects.
