1.Light Weight
Aluminium is a very light metal with a specific weight of 2.7 g/cm3, about a third that of steel. For example, the use of aluminium in vehicles reduces dead-weight and energy consumption while increasing load capacity.
2.Corrosion Resistance
Aluminium naturally generates a protective oxide coating and is highly corrosion resistant. Different types of surface treatment such as anodising, painting or lacquering can further improve this property.
3.Machining
Aluminium is very easy to machine. Ordinary machining equipment can be used such as saws and drills. Aluminium is also suitable for forming in both the hot and the cold condition.
4.Surface treatment
This surface treatment oxidizes the top layer of the aluminum, which is then compact and hard and is well-balanced with the basic material. The oxidized layer ensures excellent protection of aluminum against corrosion and wear.
5.Malleability
Aluminium has a good malleability, a characteristic that is used to the full in extruding. Aluminium can also be cast, drawn and milled.
6.Recyclability
Aluminium is 100% recyclable without any loss of its natural qualities. The re-melting of aluminium requires little energy: only about 5 percent of the energy required to produce the primary metal initially is needed in the recycling process.
