01-06-2018· Chemical processes common to preparing the metal for such surface finishing as anodizing, plating or painting put aluminum at risk for corrosion. Interestingly, aluminum inherently protects itself from this corrosion in stable conditions (pH of around 4.5-8.5) by readily oxidizing—creating a very thin layer of aluminum oxide when it comes in contact with the surrounding oxygen.
