ALLOY DESIGNATIONS
Aluminium alloy EN AW 2219 has similarities to the following standard designations and specifications:
Alloy 2219 UNS A92219, ASTM B209
DIN AlCu6Mn
TEMPER TYPES
AMS QQ-A-250/30 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.
