Anodising, or anodizing, is a technique used to modify the surface of a metal. It may provide greater corrosion resistance, create a different surface topography, and change the crystal structure close to the metal surface.The process derives its name from the fact that the part to be treated forms the anode portion of an electrical circuit in this electrolytic process.

Anodisation is frequently used to protect aluminium and titanium from abrasion and corrosion and to allow it to be dyed in a wide range of colours.

Anodized Aluminium

Anodized aluminium can be found in cookware, cameras and sporting goods due to its aesthetic and corrosion protection properties.The aluminium oxide coating is grown from and into the surface of the aluminium.As a result of this it is not prone to peeling or cracking like organic coatings such as paint. Aluminium oxide also possesses excellent thermal and electrical insulation qualities.
