Aluminum is the mostly used in form of alloys of pure aluminium in combination with other elements in order to improve the mechanical properties of the metal, especially to increase strength and corrosion resistance. The aluminium alloys in UAL are mostly of the 1000, 3000 and 5000 series Alloy elements to achieve certain properties on the final product: Fe increase the strength Si in combination with Mg for higher strength Cu increase the mechanical properties, reduces corrosion-resistance Mn increase the mechanical properties, changes deep-drawing quality Mg high strength after cold forming Cr more strength in combination with elements like Cu, Mn, Mg Ti higher strength Zn increases corrosion-resistance |
