Aluminum Alloy Materials

Aluminum alloys are classified by their primary alloying element into 8 series (1xxx–8xxx), with densities approximately one-third of steel (2.7 g/cm³). Heat-treatable grades (2xxx, 6xxx, 7xxx) achieve strength through precipitation hardening; non-heat-treatable grades (1xxx, 3xxx, 5xxx) strengthen through cold work. 6061-T6 is the general-purpose structural alloy; 7075-T6 offers aerospace-grade strength approaching mild steel; 5052 is the marine-grade workhorse. Temper designations (T6, H32, O) define the specific heat treatment and strain-hardening condition.
