Aluminum alloys are the alloys in which the predominant metal is aluminum. Copper, magnesium, silicon, tin, zinc and manganese are the typical alloying elements. Such alloys are classified into two branches namely casting alloys and wrought alloys. These can be sub-divided into heat-treatable and non-heat-treatable alloys. Primarily aluminum is used for wrought products such as rolled plate, foils and extrusions. Aluminum alloys are majorly used in aerospace manufacturing and engineering structures due to their corrosion resistance and lightweight. This book consists of contributions made by international experts. It brings forth some of the most innovative concepts and properties of aluminum alloys. A number of latest researches have been included to keep the readers up-to-date with the global concepts in this area of study.
