aluminium is very reactive with are that it forms a oxide layer.the oxide layer protects the aluminium from further oxidising.
reaction of aluminium with acid is very slow as the acid first dissolves the oxide layer and then further corrodes the aluminium.

hence aluminium called as self protecting metal.
