Aluminum's use in marine applications can increase the speed and size of boats, yachts, ferries, and ships, while improving their fuel economy, seaworthiness, safety, reliability, maintenance costs.

In many cases, integrally stiffened and mechanically interlocked extrusions are used for decks, roofing and other structures with conventional welded extrusions and sheet used for hulls and framing.

In passenger cars aluminum allows manufacturers to shave off a third of the weight compared to steel cars. In rapid transit and suburban rail systems where trains have to make a lot of stops, significant savings can be achieved as less energy is needed for acceleration and braking with aluminum cars. In addition, aluminum cars are easier to produce and contain significantly fewer parts.

Truck & Trailer (Commercial vehicles)
Aluminum reduces dead vehicle weight. When transporting high- density freight, which usually saturates the maximum gross vehicle weight, aluminum allows the loading of more goods. This translates into additional income and/or better competitiveness while at the same time reducing CO2 emissions.
