Answer 1

Answer:Aluminium and Iron both react with oxygen.Aluminium is considered better than iron because of following reasons:

Explanation:

1.In reactivity series, aluminium is placed above iron which mean it's more reactive than iron.

2.Aluminium is a good conductors of both heat and electricity.And moreover it's easy to handle

3.Aluminium don't rust easily compared to iron.It forms outer coating called aluminium oxide on oxidation and this helps to reduce further corrosion.

Answer 2

Answer:

Because Alluminium is less reactive than iron and corrodes less. Hint: Iron is more reactive metal than aluminium and corrosion of iron is called rusting. - Aluminium alloy is widely used for aerospace purposes instead of iron alloy.
