Aluminium reacts with steam a protective oxide is produced
The reaction between aluminium and steam Like the reaction between magnesium and water, it is possible to react aluminium with steam. However, the aluminium oxide produced forms a barrier on the surface of the aluminium which prevents further reaction. When
1 - Making Hydrogen from Metals - IGCSE Chemistry
Any metal that reacts quickly with water is likely to react dangerously violently with acids. Most of them would explode on contact with even dilute Hydrochloric acid. Aluminium is a little less reactive, and takes a while to start reacting because it is covered with a layer of Aluminium Oxide that protects the pure metal from the acid briefly.
