What Are Anodized and Painted Aluminium Finishes?
Anodized Aluminium is created through an electrochemical process that converts the metal surface into an integral, highly durable oxide layer. This oxide film is not a coating applied on top; it becomes part of the metal itself. The process enhances hardness, corrosion resistance, and aesthetic depth while maintaining aluminium’s natural metallic sheen.
Painted aluminium, on the other hand, involves applying an organic coating, such as polyester, polyurethane, FEVE, or PVDF onto the metal surface. While high-performance paints deliver good weather ability and colour range, they remain a separate layer that can chip, peel, scratch, or fade over time.
Because the anodic layer is inorganic and bonded to the base material, anodized Aluminium material does not flake or delaminate. Painted surfaces rely heavily on coating integrity and surface preparation.
Is anodized aluminium more durable than coated aluminium?
Yes. Since anodizing converts the aluminium surface itself into a hardened oxide layer, it significantly surpasses coated aluminium in scratch resistance, UV stability, and corrosion protection. Paint, being a surface film, is more vulnerable to mechanical wear and environmental degradation
