Anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. ... This aluminum oxide is not applied to the surface like paint or plating, but is fully integrated with the underlying aluminum substrate, so it cannot chip or peel.

What's the difference between anodized and painted?

In general, anodizing is less expensive than painting, with the exception of coil painted products. ... Anodizing gives aluminum a deeper, richer metallic appearance than is possible with organic coatings. This is because an anodized coating is translucent, and one can see the base metal underneath the coating.

Does anodized color wear off?

Anodize does not come off.

Anodize is fairly permanent because it actually “grows” out of the base aluminum material. However, it can be removed with an acid wash, and it can indeed be worn off.
