ALLOY DESIGNATIONS
AMS QQ-A-250/12, 7075 has similarities to the following standard designations and specifications ;
Alloy 7075, UNS A97075, ASTM B209
AMS 4044, AlZn5.5MgCu, DIN 3.4365
EN 3335
TEMPER TYPES
7075 is supplied in a wide range of tempers:
- O - Soft
- T6 - Solution heat-treated and then artificially aged.
- T62 - Solution heat-treated and then artificially aged. Applies to test material heat-treated from annealed or F temper or to products heat-treated from any temper by the user.
- T651 - Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate, 1% to 3% for rolled or cold-finished rod and bar, 1% to 5% for hand or ring forging and rolled ring) and then artificially aged. The products receive no further straightening after stretching.
- T6510 - Solution heat-treated, stress-relieved by controlled stretching (permanent set 1% to 3% for extruded rod, bar, shapes and tube, 0.5% to 3% for drawn tube) and then artificially aged. The products receive no further straightening after stretching.
- T6511 - Same as T6510 except that minor straightening is allowed after stretching to comply with standard tolerances
- T73 - Solution heat-treated and then artificially overaged in order to achieve the best stress corrosion resistance.
- T7351 - Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate, 1% to 3% for rolled or cold-finished rod and bar, 1% to 5% for hand or ring forging and rolled ring) and then artificially overaged in order to achieve the best stress corrosion resistance. The products receive no further straightening after stretching.
- T73510 - Solution heat-treated, stress-relieved by controlled stretching (permanent set 1% to 3% for extruded rod, bar, shapes and tube, 0.5% to 3% for drawn tube) and then artificially overaged in order to achieve the best stress corrosion resistance. The products receive no further straightening after stretching
- T73511 - Same as T73510 except that minor straightening is allowed after stretching to comply with standard tolerances.
- T76 - Solution heat-treated and then artificially overaged in order to achieve a good exfoliation corrosion resistance.
- T76511 - Solution heat-treated, stress-relieved by controlled stretching (permanent set 1% to 3% for extruded rod, bar, shapes and tube, 0.5% to 3% for drawn tube) and then artificially overaged in order to achieve a good exfoli-ation corrosion resistance. The products receive no further straightening after stretching, except that minor straightening is allowed after stretching to comply with standard tolerances.
