When water continually sprays on the
aluminum sheet, how to avoid corrosion of
aluminum sheet and keep its water resistance?Don’t worry about it, after aluminum contacts water or air, a layer of oxide film will generate on its surface to separate aluminum from the water or air and protect it, so it won’t be erosive.aluminum will react with oxygen, generating dense Al2O3 oxide film on the surface, once the pure aluminum is exposed in air, it will react with air, generating oxide film to protect it.Other related question
