Abstract
Aluminum, the third largest element available on the earth’s crust is the second highest consumed metal by weight and stands a distant second to iron and its alloys. The lower consumption by weight is in a large part a consequence of its low density, and is one of the prime advantages of this metal. This low density combined with the attractive strength properties of modern Al alloys makes it ideal for structural applications. The other distinctive properties of Al and its alloys include high ductility, low electrical resistance and high corrosion resistance. Such combination of desirable properties along with low density makes Al and its alloys an ideal replacement for steel, though the relatively high cost and low weldability has limited its scope to more niche applications.
