What is Aluminum Anodizing?

There are several types of anodizing: chromic acid anodizing (type I), sulfuric acid anodizing (type II) and hard coat anodizing (type III). In this series we will focus on sulfuric acid anodizing (SAA) also called anodizing type II as it is used in 70 % of all anodized products. 

Anodizing is an electrochemical process to thicken the naturally formed oxide layer of aluminum. Through this process, the oxide layer grows from nanometers to microns in thickness. As a result, the properties of the aluminum product change. For example, the product gains a higher corrosion resistance, coloring ability, and a consistent appearance. More so, anodizing makes aluminum more versatile for other applications. This means that an anodized leg prosthesis will not be scratched while climbing a mountain and will not be damaged by a swim in the sea. The thickened anodic layer gives the soft aluminum material a protective surface.

Owner of AluConsult & Anodizing School

At Anodizing School I transform my practical and theoretical knowledge into actionable steps that improve your anodizing process today. Our online courses help you create a more consistent high-quality anodic coating on aluminum. With 25 years of experience in the anodizing industry, I understand which anodizing practices work best in the real-world conditions of an anodizing line. At Anodizing School I want to bring the better-than-best practice based on scientific research and hands-on practice into your aluminum business.
