Aluminium is widely used in the automotive and transportation sector for its light weight and strength, which improve fuel efficiency and performance. It is used in vehicle body panels, engine blocks, and transmission systems. Railway coaches and metro trains use aluminium for doors, flooring, and side panels to reduce weight and resist corrosion.

In aerospace, aluminium forms the core structure of aircraft due to its high strength-to-weight ratio. Shipbuilding and marine vehicles use aluminium for hulls and fittings to withstand harsh environments. Even bicycles, trucks, and buses incorporate aluminium in frames and structural parts.
