4.3 Material Components/Denitions

4.3.1 Alloy Aluminum alloys are alloys in which aluminium is the predominant metal. The
typical alloying elements are copper, magnesium, manganese, silicon, and zinc. Selecting
the right alloy for a given application entails considerations of its tensile strength, density,
ductility, formability, workability, weldability, and corrosion resistance. In aluminum
proles systems the most used alloys are 6060 and 6063.
