“…The aluminum alloys are widely applied in various industries due to their ability to combine strength and lightness [1]. In comparison with other construction materials, Al is characterized by a low melting temperature, in the range between 590 and 660 • C [2], excellent electrical [3] and thermal conductivity [4] and high processing ability by casting, stamping, drawing, spinning, rolling and hammering [5,6]. The mechanical properties, particularly hardness and strength, of these alloys can be improved by alloy additions such as copper, manganese, magnesium, zinc, silicon and others [1,[7][8][9].…”
