Detailed Solution

Al is used as a reducing agent in aluminothermy because

Aluminum, a more reactive metal, is therefore utilized for them. It may convert some metal oxides, like Ferric Oxide and Dichromium trioxide, into equivalent metals because of its great affinity for aluminum. Aluminum serves as a reducing agent in the aluminothermic process, converting other metal oxides to the corresponding metals.
