The most abundant metal
Aluminium is the most abundant metal and it is the third most common element, comprising 8 percent of the earth’s crust. Its versatility makes it the most widely used metal after steel.
Although aluminium compounds have been used for thousands of years, aluminium metal was first produced 170 years ago. In the 100 years since the first quantities of aluminium were produced, worldwide demand for aluminium has grown to around 29 million tons per year. About 22 million tons is new aluminium and 7 million recycled aluminium scrap.
Great qualities
Pure aluminium is ductile, corrosion resistant and has a high electrical conductivity. It is widely use for foils and conductor cables, but alloying with other elements is necessary to provide the higher strengths needed for other applications. Aluminium is one of the lightest engineering metals, having a strength to weight ratio superior to steel.
By utilizing various combinations of its advantageous properties such as strength, lightness, corrosion resistance, recyclability and formability, aluminium is being employed in an ever-increasing number of applications. This array of products ranges from structural materials through to thin packaging foils, in the building, aircraft, car, naval industry and others.
