Anodizing
Electrochemical surface treatment that creates a hard, corrosion-resistant oxide layer on aluminum.
1 companies
Anodizing is an electrochemical process that converts the surface of aluminum into a durable, corrosion-resistant aluminum oxide layer. It increases surface hardness, improves wear resistance, and allows for coloring through dye absorption. It is widely used for aerospace, architectural, and consumer product applications.

Anodizing FAQ
What is the difference between Type II and Type III anodizing?
Type II (sulfuric acid) anodizing produces a coating 0.0002 to 0.001 inch thick for general corrosion protection and decorative applications. Type III (hard coat) anodizing produces a thicker coating of 0.001 to 0.004 inch for maximum wear resistance and hardness in demanding applications.
