〉20191227ヂ No. Aluminium stops corroding once a strong oxide layer is formed. Aluminium is a fairly reactive metal. The reason why it usually survives in air and water under normal conditions is because the aluminium oxide layer on the surface is very strong and normally protects the metal from further attack.
