How does anodized aluminum compare against other metals in terms of corrosion resistance?

Aluminum is naturally corrosion resistant and does not break down or degrade with exposure to water or humidity like other metals. In terms of chemical resistance anodized aluminum performs best when chemical exposure is limited to pH levels between 5 and 9. We recommend thicker anodic films when corrosion resistance is a key element of the finished product.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest.
