Aluminium has quickly become the irreplaceable metal in many industries because of its features like lightness, easy formability, resistance to corrosion, alloying, gaining high resistance with heat treatment, high heat and electricity conductivity and colourability via covering its surface in various ways.

It is generally found as bauxite element in the nature and is known with its high resistance to oxidation. The basis of this resistance is its passivation characteristics. Mineral from which aluminium can be retrieved are Bauxite, Nepheline, Alunite and Clay. Its density is approximately one third of steel or copper. It should not be used less than 0.70 mm of supporting surface thickness in Sandwich panels and of plate thickness in decks. It shall be flat or its surface shall be subjected to embossing.

The characteristics of Aluminium: 1. Aluminium is light. 2. Aluminium is resistant to weather conditions, foods and most of the liquids and gasses used in daily life. 3. Aluminium has a high capacity of reflecting. With the contribution of its grey-white colour to this feature, it has an appearance charming for both interior and exterior architecture. This beautiful appearance of Aluminium can be protected for long periods with applications such as anodic oxidation.

Aluminium is an elastic material. Therefore it is resistant to sudden impacts. Also, its resistance does not decrease in low temperatures (The resistance of steels to sudden impacts decrease in low temperatures). 5. Aluminium is a metal that can be processed easily. 6. Aluminium conducts the heat and electricity as good as copper.
