It is evident that optimization of the anodization process is critical to the mechanical properties, or more specifically, scratch resistance of the anodized aluminum oxide layer in this case. A. The aluminum oxide is fused into the base metal, eliminating any chance of it peeling away or chipping. Since chromic acid by itself does not attack Aluminium, post-anodizing cleaning and rinsing is not as critical as with other processes. The anodizing process forms a layer of oxide on a metal part, effectively increasing corrosion resistance, and also enhancing visual qualities and keeping the surface from being scratched. You might not realize it, but you probably interact with products and parts that have been anodized on a daily basis. While the standard 6000 series aluminum is plenty strong for a watch, 7000 series aluminum offers roughly double the hardness and twice the tensile strength, approaching figures typically seen in mild steel.
