ALUMINUM TEMPER DESIGNATIONS
The temper designation follows the alloy code and is separated by a hyphen.
-F As Fabricated: Applies to products of rolling or forming where there is no special control over the thermal or
work-hardening conditions. Since mechanical properties may vary widely, no limits have been assigned. This
temper usually applies to sheet products which are at intermediate stages of production.
-H Strain-Hardened: Applies to wrought products which are strengthened by cold-rolling or cold-working.
-O Annealed: Applies to wrought products which have been heated above the recrystallization temperature to
produce the lowest tensile strength condition of the alloy.
