Aluminium alloys have been one of the widely used metal materials in many industries, including art and architecture. To create a more durable substance, aluminium is normally treated with metal finishing techniques such as anodising, bead blasting, and other pre-treatment methods.
Among the techniques, anodising is most preferred by many manufacturers for it creates a durable finish with a hardness level second to that of diamond. Anodising aluminium involves an electrochemical process that strengthens the metal surface by adding a layer of protective anodic coating. After the entire process, the anodic coating becomes part of the metal, but it has a porous structure that allows for enhancement procedures such as inorganic colouring, which opened doors for many decorative functions.
