Type II Anodize
Sulfuric Acid Anodizing
Type II anodizing, also known as sulfuric acid anodizing, is one of the most widely used and versatile aluminum finishing processes. It creates a thicker, harder, and more porous oxide layer than Type I anodizing, delivering superior corrosion resistance, wear protection, and durability. The porous structure of the anodized layer allows for vibrant color dyeing, making Type II anodizing ideal for applications where aesthetics and performance are required.
