Soft, lightweight, corrosion-resistant alloy conducts both heat and electricity; available in a number of types to suit a variety of applications. ALUMINUM TEMPERS H14 (1/2 Hard) Material is strain-hardened only (without additional thermal treatment) to a half-hard temper. H32 (1/4 Hard) Material is strain-hardened and mechanical properties are stabilized with supplementary thermal treatment to a quarter-hard temper. T3 Material is solution heat treated, cold worked, and naturally aged to a substantially stable temper. T351 Aluminum is treated and aged the same as T3 and then stretch-stress relieved. T4 Material is solution heat treated and naturally aged to a substantially stable condition. T6 Aluminum is solution heat treated and then artificially aged. T651 Material is solution heat treated, artificially aged, and then stretch-stress relieved. Specifically refers to plates and cold-finished bars and rods. T6511 Extruded aluminum is solution heat treated, artificially aged, and then stretch-stress relieved. T7351 Aluminum is solution heat treated, overaged and stabilized, and then stretch-stress relieved.
