Durability Aluminium alloys have excellent durability and corrosion resistance, but their behaviour can be influenced by the way in which they are used. Aluminium’s natural affinity with oxygen results in the formation of a transparent oxide film when aluminium is exposed to air. This film is extremely hard, chemically stable, corrosion resistant, and adheres strongly

Alloy and Temper The four-digit system used for designating the alloys is an international one which has been adopted by all major aluminium producers. The first digit indicates the alloy group. The second digit indicates modifications of the original alloy or impurity limits. The last two digits identify the specific alloy and aluminium purity. Alloys

EngGeneral Characteristics A wide variety of mechanical characteristics, or tempers, are available through various combinations of cold working and heat treatment. A good resistance to corrosion on surfaces exposed to the atmosphere is achieved due to the formation of a thin transparent oxide film that protects the substrate from further oxidisation. Attractive appearance, low maintenance,
