Summary: Aluminum is the most abundant metal in the earth's crust (8.1%), but is not found in Nature as the free metal. Aluminum metal is coated with a thin film of aluminum oxide (Al 2 O 3 ) which prevents further corrosion. Aluminum was very expensive before 1886 when a convenient method of obtaining aluminum metal from the ore was discovered. Aluminum is known as aluminium in countries other than the USA.
