ALLOY DESIGNATIONS

Aluminium alloy 2124 has similarities to the following standard designations and specifications:

AMS 4221, AMS QQ-A-250/29,  Alloy 2124,   UNS A92124

DIN AlCuMg2, ISO AlCu4Mg, EN 2422

 

TEMPER TYPES

2024 is supplied in below tempers:
T351 is intended to provide material with low residual stresses and thus minimal distortion during machining, but does not provide optimal corrosion resistance.

  • T351 - Solution heat treated then stress relieved by stretching. Equivalent to T4 condition.
  • T851 - Solution heat treated then stress relieved by stretching then artificially aged.
  • T8151

 

SUPPLIED FORMS
