ALLOY DESIGNATIONS
EN 2512, 7175 has similarities to the following standard designations and specifications ;

 

Alloy 7175, UNS A97175, ASTM B209

EN 2512, AlZn5.5MgCu, DIN 3.4364

AIR 9048, ABS 5064

 

TEMPER TYPES

7175 is supplied in a wide range of tempers:
  • 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.
