Automotive

The combination of acceptable cost, low component mass (derived from its low density), appropriate mechanical properties, structural integrity and ease of fabrication are also attractive in other areas of transport. There are now very many examples of its use in commercial vehicles, rail cars both passenger and freight, marine hulls and superstructures and military vehicles.

Volume car production now includes aluminium as engine castings, wheels, radiators and increasingly as body parts. For general production the 5000 and 6000 series alloys provide adequate strength combined with good corrosion resistance, high toughness and ease of welding. In aircraft the very strong 2000, 7000 and 8000 series alloys are preferred, and in military vehicles the weldable 7000 series alloys can provide ballistic properties to match steel armour.
