DIN AlZn6Mg2Cu

 

TEMPER TYPES

7150 is supplied in a wide range of tempers:
 

  • T6151 - Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate) and then artificially aged in underageing conditions to improve formability. The products receive no further straightening after stretching.
  • T61511 - Solution heat-treated, stress-relieved by controlled stretching (permanent set 0.5% to 3% for sheet, 1.5% to 3% for plate) and then artificially aged in underageing conditions to improve formability. The products receive no further straightening after stretching except that minor straightening is allowed after stretching to comply with standard tolerances.
  • T7751 - Solution heat-treated, stress-relieved by controlled stretching and then artificially overaged in order to achieve a good exfoliation corrosion resistance. The products recieve no further straightening after stretching.
  • T77511 -   Solution heat-treated, stress-relieved by controlled stretching and then artificially overaged in order to achieve a good exfoliation corrosion resistance. The products recieve no further straightening after stretching.except that minor straightening is allowed after stretching to comply with standard tolerances.
