Al has limited use because of its low mechanical strength though they are corrosion resistant than steel, but are used in thin beverage cans because

CO2 s internal pressure gives extra rigidity

Tin is applied ectrolytically to steel cans to give corossion resistance to steel cans and hence called

Tin cans
