Aluminum Alloy Series 1xxx–8xxx Overview
The wrought aluminum designation system groups alloys primarily by principal alloying element, from commercially pure 1xxx alloys through specialized 8xxx compositions.
Material basis
1xxx is commercially pure aluminum; 2xxx Al-Cu; 3xxx Al-Mn; 4xxx Al-Si; 5xxx Al-Mg; 6xxx Al-Mg-Si; 7xxx Al-Zn-Mg(-Cu); 8xxx covers other alloy systems.
Applications
Use this overview to identify the family before selecting a specific alloy and temper.
Common grades / designations
Properties vary greatly within each series and depend on temper, thickness and product form.
