Aluminium is used for aircraft, trains, overhead power cables, saucepans and cooking foil. Titanium is used for fighter aircraft, artificial hip joints and pipes in nuclear power stations.
Aluminium, also spelt aluminum, is the most common metal in the world, and the third most common element (after oxygen and silicon). It is durable and lightweight, and is a very important metal for making planes out of. Aluminium is highly reactive and you cannot find pure aluminium in the same way you can find pure gold or copper, so it was once considered a rare precious metal.
