Corrosion: Reasons and solution

Acids and bases break down the oxide layer, thereby opening up the raw aluminium surface. If aluminium is exposed to very strong acid or alkaline environments outside the pH range 4 to 9, violent corrosion will occur in the form of metal pitting. Bases break down the aluminium faster than acids - for example concentrated caustic soda reacts so violently with aluminium that it can start to boil.
