What is Anodizing, Why Anodize, and Why you should Anodize with Hager?

Hager offers several anodized aluminum products, but have you ever wondered what ‘anodized’ means and why it is done?

Aluminum anodizing is an electrolytic process that creates a controlled and uniform pore structure or anodic oxide layer on an aluminum surface. Unlike plating which is an electrolytic process that builds or bonds finishing metals to a surface in a cathodic or “throwing” process, anodize is an anodic process that consumes some of the surface creating a barrier layer and then “grows” the pore structure on top. As the anodize finish is an integrated part of the surface, it is not susceptible to cracking or peeling like paint.

Why should you anodize parts?

Anodizing an aluminum part will stop the natural oxidation process, maintaining a uniform finish for much longer than unfinished aluminum. Unlike iron-based metals that rust (oxidize) red when unfinished, unfinished aluminum will naturally oxidize white. Also, unfinished aluminum has a very delicate surface, leaving it vulnerable to wear and scratches. When a part is anodized, the surface becomes much harder and much more resilient.


Why should you Anodize with Hager Companies?
