As it is highly resistant to corrosion, aluminium is one of the most preferred metals for both industrial and aesthetic purposes. When anodised, an aluminium product may last longer, look better, and even becomes 100% recyclable for other applications. This saves a lot of energy and other resources needed to produce aluminium straight from raw materials.
How Anodising Helps Aluminium
Aluminium is already highly resistant to corrosion in itself because of its inherent protective oxide layer. The anodising process enhances this property, along with its other fine characteristics, to create a more durable and versatile product. A thin yet strong finish, called anodic coating, is added to the aluminium surface, resulting in the second hardest man-made substance next to diamond—anodised aluminium.
