Aluminum is one of the most popular elements in nature. Third most abundant element after oxygen and silicon the bauxite - the main mineral from which it is derived- constitutes about 8% of the Earth's surface is by far the youngest among metals of industrial use being produced for the first time on a large industrial scale just over 100 years ago.
THE PRODUCTION COST
Produce the aluminium from scratch, has an energy cost of 13 kWh/kg. The production of recycled aluminum reduces this cost by 95%. In the Worldwide, about 31 million tonnes of aluminum per year are produced, of which 7 million tonnes come from recycling.
The aluminium can be recycled 100% and infinitely without losing its original features that remain unchanged indefinitely, also following numerous recycling phases or when from primary aluminum the metal acquires the definition of "recycled aluminum" or "secondary aluminum".
At equal volume, aluminum weighs about 1/3 of copper and steel. Even for this reason, much of the modern transportation means are built using high aluminum percentages.
THE CORROSION RESISTANCE
The aluminium oxidizes immediately in contact with air, creating a superficial protection that makes it water-resistant and to some chemicals. This feature makes it the most used metal in the transport, building and construction industries.
DUCTILITY AND MALLEABILITY
The aluminum is easily workable and is suitable for both high and low temperatures.
THE REFLECTIVE CAPACITY
It diffuses and reflects the light by reducing the dispersion of brightness from the light source and thus favouing the energy saving.
THE ANTIMAGNETIC CHARACTERISTICS
This feature allows it to be used for the construction of radio, radar and stereo equipment.
