Aluminum is the optimal choice for the manufacturing of new cars and trucks both for its ecological impact and durability. Aluminum is an efficient material: it allows to cut vehicle weight and so to conserve field or battery power. It is sustainable, in fact it has the smallest total carbon footprint among all competing materials. Federal regulators and leading automakers agree that well-designed, lower weight vehicles can be as safe as or even safer than heavier vehicles. The U.S. military uses high-strength aluminum alloys in combat vehicles because of the resistance of this material. The use of aluminium allows the creation of high-performing vehicles, with faster acceleration, shorter braking and better handling. For all these reasons the use of aluminium in transportation is fast-growing.
