The physical characteristics of coil anodised aluminium have been explained by Lorin Industries, stating that it provides greater durability and aesthetics than other metal products. The coil anodising process from Lorin protects aluminium from oxidation, scratching, and other hazards far better than natural oxidising, and offers more protection than is available for other metals.
While aluminium creates its own protective oxide layer naturally, coil anodising is an electro-chemical process that grows the aluminium oxide layer from the base aluminium, bonding it to the aluminium at the molecular level. It is not a coating; it is part of the aluminium. Therefore, it cannot chalk, chip, flake or peel like coatings or paint often do. The anodising process produces an anodic layer 2,500 to 25,000 times thicker than that of the naturally occurring oxide layer providing far greater corrosion and abrasion resistance than other metals or coatings.
Controlling the oxidation process through continuous coil anodising creates a clear, translucent aluminium oxide layer that shows off the beauty of the natural metal. This anodic layer can also be coloured, allowing the products to be given a specific look, even simulating other natural metals. Additionally, because this layer is created through the continuous coil process, the colour and finish are consistent over every square inch of the aluminium. Furthermore, Lorin believes that its Anodised Aluminium will not chip, flake or peel.
The translucent crystalline structure of the anodic layer allows the metal to reflect and refract light. This crystalline aluminium oxide layer is actually part of the corundum family of gemstones like a sapphire, and is reportedly second only to diamonds in terms of hardness, leading to lasting beauty, performance and durability.
