What is Aluminum Anodizing?
Aluminum anodizing is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide. It’s a hard finish that is environmentally safe, non-toxic and easy to maintain. Its’ long lasting durability and corrosion resistant properties, make it a finish that is second to none
Why is a thick Anodic coating important for Aluminum?
Most of the wear resistance that the Aluminum will ultimately exhibit isn’t from the alloyed aluminum that makes up the bulk of the material, but the thin Aluminum Oxide surface coating. To refresh your chemistry a little (or maybe you don’t need it!) Aluminum Oxide is the same thing that gives Ruby and Sapphire their hardness, a 9 on the Mohs Hardness scale. Aluminum Oxide is very commonly used as an abrasive in the metal fabrication business because it just that hard. Unfortunately, the Aluminum underneath the anodization isn't nearly as hard, and can be deformed. A thicker anodic layer provides more integrity and greater wear resistance.
