ALLOY DESIGNATIONS

Aluminium alloy AMS 4094, 2219 has similarities to the following standard designations and specifications:

AMS QQ-A-250/30,  Alloy 2219,  UNS A92219; ISO AlCu6Mn

 

TEMPER TYPES

2219 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
  • T31 - Solution heat treated, cold worked and naturally aged
  • T37 - Solution heat treated and naturaly aged to a substantially stable condition
  • T62 - Solution heat treated then artificially aged by the user
  • T81 - Solution heat treated, cold worked then artificially aged
  • T87 - Solution heat treated, cold worked then artificially aged
  • 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.
  • F
