Retarded question but do metals last longer when they're thicker? I'm thinking of getting aluminum roofing and most manufacturers say their plates last ~50 years. I wonder if i would buy aluminum plates that were twice as thick as theirs, would they last 100 years? Or 200 years since it's four times the volume?

I'm not entirely sure how corrosion works but since oxygen is needed my guess is that it gradually corrodes from outside to inside, so more volume should mean it takes longer to corrode down to the center right? Or does aluminum corrode evenly inside no matter the thickness?
