Satin anodized aluminum
Satin Clear aluminum anodizing finish is one of the most popular surfaces for many aluminum applications. The look of aluminum right after the extrusion process is a naturally occurring oxidation producing a finish often called Mill Finish. The naturally occurring oxidation protects the aluminum surface with an oxide layer that can be further enhanced with anodizing. The chemical solution used to anodize the aluminum involves acids that wash and clean the material. The end result of the anodizing process is that the clear satin aluminum will have a thicker layer of oxide that creates an extremely consistent satin luster like appearance.
