ALLOY DESIGNATIONS
EN AW 7175 has similarities to the following standard designations and specifications ;
Alloy 7175 UNS A97175, ASTM B209
DIN AlZn5.5MgCu
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.
SUPPLIED FORMS
7175 is supplied in plate, bar and extrusions.
- Plate
- Round Bar / Bar
