The growth in usage and production of Al continues to increase (Davis 1999). The extensive use of Al lies in its strength:density ratio, toughness, and to some degree, its corrosion resistance.

Aluminum Oxidation Is Aluminum Corrosion-Resistant durability and corrosion of aluminium and its alloys

Generally speaking, aluminum and its alloys have excellent resistance to corrosion. Aluminum in its natural state, commercially pure or 1xxx aluminum, has the best corrosion-resistance, but that quality is compromised as alloys, particularly copper and iron but also magnesium or zinc, are added. The alloying elements used to achieve desirable properties of most commercial aluminum alloy groups are listed (plate) Aluminum and Aluminum Alloys - NIST(steel) Appropriately alloyed and treated, aluminum can resist corrosion by water, salt, and other environmental factors, and by a wide range of other chemical and physical agents.

In general, aluminium alloys are characterized by a relatively low density (2.7 g/cm 3 as compared to 7.9 g/cm 3 for steel), high electrical and thermal conductivities, and a resistance to corrosion in some common environments, including the ambient atmosphere. The chief limitation of aluminum is its low melting temperature (660°C), which restricts the maximum temperature at which it can be used.(plate) CHAPTER 11 METAL ALLOYS APPLICATIONS AND (steel) Aluminum and its Alloys Low density (~2.7 g/cm3), high ductility (even at room temperature), high electrical and thermal conductivity and resistance to corrosion BUT law melting point (~660°C) Main types of Aluminum Alloys - Wrought Alloys - Cast Alloys - Others e.g. Aluminum-Lithium Alloys(plate) CORROSION RESISTANCE OF ALUMINIUM - Conways(steel) the information in this book or in its use.

The causes and forms of aluminum corrosion are associated with the flow of electric current between anodic and cathodicregions. The intensity of corrosion in this case depends on the difference of potential of the two regions, which is due to microstructural defects caused by fabrication, welding and other joining methods.(plate) Understanding Aluminum Corrosion(steel) Jun 27, 2019The corrosion attack on aluminum alloys in soil depends on the composition and climatic conditions of the soil. In dry, sandy soil, corrosion is negligible, but in wet, acidic or alkaline soils, the attack may be severe. Most gases, in the absence of water and at or near room temperature, have little or no action on aluminum-base alloys.
