Aluminium. Aluminium is the most widely used metal after iron. It has a low density, is malleable and easily worked. It is also corrosion resistant and a good conductor of both heat and electricity. With the exception of corrosion resistance, all these properties can be improved or augmented by alloying aluminium with small amounts of other metals.
