What is Anodizing?

Anodizing is a conversion coating process that involves immersing aluminum into an acid electrolyte bath and passing an electric current through it. This creates a robust and fully integrated coating of aluminum oxide on the surface of the aluminum, replacing the naturally occurring oxide layer and penetrating through to the base metal. Unlike paint, anodizing doesn’t chip or flake.
