Anodization is an advanced electrochemical process that forms a protective aluminum oxide (Al₂O₃) layer on the metal's surface. This enhances corrosion resistance, durability, and aesthetic appeal.
The aluminum is placed in a sulfuric acid (H₂SO₄) electrolyte as the anode, creating a porous oxide layer. This layer can range from 5 to 30 microns in thickness, depending on the application.
