Question

aluminium protect itself against corrosion discuss why it is necessary to Anodize aluminum to make it corrosion resistant

Answer 1

aluminium is high reactive metal than iron. so it easily oxidised to form aluminium oxide and protects inner core of the metal from rusting

Answer 2

Answer:

Aluminium protects itself against corrosion upon exposure to air by forming a layer of aluminium oxide. If this layer is made more uniform, it protects the aluminium underneath more effectively. Thus, this is done by a process called anodizing to make it corrosion resistant.
