Aluminium - Aluminium is a pure metal. It is soft and malleable and conducts heat and electricity well. However in its purest form, it is useless as an engineering material and is always alloyed to improve its properties. It is also extremely lightweight. For this reason it is a material that is extensively used in the aircraft industry. Aluminium will polish up and shine, but over a fairly short period of time the shine will disappear and a thin oxide layer will appear over the metal. This is an inert film of oxide and, unlike
