Understanding Aluminum Alloys

摘要

One of the most important things to understand about using aluminum for part or product design purposes is that pure aluminum is only used in a limited way commercially. The majority of extrusions are made from aluminum alloyed with other elements. The most common elements used are magnesium (Mg), silicon (Si), manganese (Mn), zinc (Zn) and copper (Cu). Most aluminum extrusions are made from the following alloy series: 1000 series Al; 3000 series Al + Mn; 5000 series Al + Mg; 6000 series Al + Mg + Si; and 7000 series Al + Zn + Mg.
