ALLOY DESIGNATIONS

Aluminium alloy 2024 has similarities to the following standard designations and specifications:

AMS QQ-A-250/4,  Alloy 2024,  UNS A92024

AMS 4041,  DIN AlCuMg2

AMS 4036, ISO AlCu4Mg

 

TEMPER TYPES

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

  • O - Soft
  • T3 - Solution heat treated, cold worked and naturally aged
  • T42 - Solution heat treated and naturaly aged to a substantially stable condition
  • T81 - Solution heat treated, cold worked then artificially aged
  • T351 - Solution heat treated then stress relieved by stretching. Equivalent to T4 condition.
  • T4 - Solution heat treated and naturaly aged to a substantially stable condition
  • T62 - Solution heat treated then artificially aged by the user
  • T851 - Solution heat treated then stress relieved by stretching then artificially aged.
  • T361 - Solution heat treated then stress relieved by stretching.
  • T72 - Solution heat treated then specially artificially aged for resistance to stress corrosion
  • T861
