Anodising is the process of electrolytic oxidisation.
An electric current is passed through a liquid solution containing ions to produce oxidisation, a process that usually occurs naturally when aluminium is exposed to the elements. Aluminium oxide protects the metal’s surface area by increasing the durability and thickness and greatly improving its resistance to corrosion and wear.
Anodising is typically carried out in a series of tanks filled with solution. Components are placed in the solution and a voltage is applied, causing an oxide film to form on the metal surface at a desired rate and thickness.
Anodised aluminium produces a silver finish that has a deeper, richer, metallic appearance than is possible to obtain with organic coatings such as paints and does not peel, chip, flake or blister. Anodised metals provide excellent long-term resistance to the harsh ultra-violet conditions in Australia and should be an important consideration whenever a lasting, attractive appearance is required.
