7 Technical & commercial information Aluminum properties Lightness The aluminum is an extremely light metal: its specific weight is 167.1 lbs/ft 3 , that means only one third of the specific weight of the steel. Resistance The resistance of aluminum can be optimised with the addition of low quantities of other metals. Some particular alloys can make the resistance of aluminum similar to the steel. Resistance to corrosion The spontaneous oxide coating protects the aluminum making it particularly resistant to corrosion. This feature can be improved by means of specific surface treatments. Machinability The aluminum can be utilizationd in the most various applications, thanks to the possibility to employ alloys which raise and complete its mechanical features. Inflammability and fire resistance Thanks to its refractoriness features, the aluminum can be employed in the buildings and in the transport sector as well.
