Aluminum anodize

Aluminum anodize is the process of hardening aluminum by electrochemical method. The method is a way of actively creating an extremely strong oxide layer on aluminum and its alloys. And the strength of this oxide layer is hundreds of times greater than that of naturally formed aluminum oxide and can rank its hardness after diamond. Therefore, aluminum anode is considered the most advanced material today.

Simply put, aluminum anodizing is the process of putting aluminum parts into an electrolyte (the electrolyte solution can be sulfuric acid or chromic acid..), chemical reactions will occur to create on the surface of the aluminum part, a thin layer of aluminum oxide film (in µm). This oxide film has very hard properties, excellent resistance to corrosion and abrasion.

A special feature is that this oxide film has a very good color absorption ability to create products with a variety of colors. Therefore, aluminum anodizing technology is becoming more and more popular in the production process of aluminum profiles.
