Assignment Details Aluminium alloys are very widely used in the industry as structural metals, second only to steel. Pure aluminium is very soft, light in weight and low melting point which makes it quite popular for various applications. However, adding alloying elements to aluminium enhances various physical properties making it even stronger and versatile for numerous engineering applications. Answer the following questions 1. Identify the following information for pure aluminium: Atomic number Atomic mass Atomic radius Crystal structure Density Periodic...
