Solution

Following chemical reaction an example of displacement reaction and redox reaction.

Fe₂O₃ + 2Al → Al₂O₃ + 2Fe

As aluminium is more reactive than iron it will displace iron from iron oxide and forms aluminium oxide.
Iron loses oxygen and aluminium gains oxygen, so iron is reduced and aluminum is oxidized.

Since it is a highly exothermic reaction, it is used for welding purposes.
