Aluminum temper designation

Aluminum is usually named in 4 numerical digits and follows by a temper designation. For example, 5052-H32. 5052= Aluminum/magnesium alloy, H3 = strain hardened and stabilized by low temperature heating. The last digit after the second representing the hardness on the Aluminum. In this case 2 = 1/4 hard.Aluminum/magnesium alloy

Aluminum

H Strain hardened (cold worked) with or without thermal treatment.
H1 Strain hardened without thermal treatment.
H2 Strain hardened and partially annealed.
H3 Strain hardened and stabilized by low temperature heating.
Last digit A last digit represent hardness.
Hx2 = 1/4 hard.
Hx4 = 1/2 hard.
Hx6 = 3/4 hard.
Hx8 = full hard.
O Full Soft (annealed).
T1 Heat treated to produce stable tempers.
T2 Partially solution heat treated and naturally aged.
T3 Solution heat treated and cold worked.
T4 Solution heat treated and naturally aged.
T5 Partially solution heat treated and artificially aged.
T51 Stress relieved by stretching.
T510 No further straightening after stretching.
T511 Minor straightening after stretching.
T52 Stress relieved by thermal treatment.
T6 Solution heat treated and artificially aged.
T7 Solution heat treated and stabilized.
T8 Solution heat treated, cold worked, and artificially aged.
T9 Solution heat treated, artificially aged, and cold worked.
