The resulting alloys, occasionally much more malleable than aluminium itself, can be moulded into many different shapes, such as the aerodynamic arc of a airplane's wings, or its tubular fuselage. And whereas iron rusts away when exposed to The weather, aluminium kinds a microscopically slender oxide layer, safeguarding its area from further corrosion. With this hefty CV, it's not astonishing to uncover aluminium in a number of other cars, including ships, cars and trucks, vans, trains and bicycles.
