Aluminum is a widely used metal second only to iron and steel in overall industrial consumption. It is the most popular of the “light” metals because of its superior materials properties especially its light weight or low density. It is used in a wide range of products such as electronic components in cameras and audio equipment, and automotive, aerospace and furniture. Anodizing is the electrochemical process which increases the thickness of the natural oxide layer on the aluminum surface. Benefits of anodizing include: Enhanced corrosion resistance, Improved wear resistance, Increased surface hardness, Ability to dye the aluminum for decorative purposes.
