7049 has very high mechanical properties (tensile strength) and good machinability. Offers a high resistance to stress corrosion cracking. Typically used in aircraft structural parts.
ALLOY DESIGNATIONS
Aluminium alloy AMS 4200, 7049 has similarities to the following standard designations and specifications ;
Alloy 7049, UNS A97049, ASTM B209
TEMPER TYPES
7049 is supplied in a wide range of tempers:
- T7351 - Solution heat-treated, stress-relieved by controlled stretching and then artificially overaged in order to achieve the best stress corrosion resistance. The products receive no further straightening after stretching.
- T73511 - Solution heat-treated, stress-relieved by controlled stretching (permanent set 1% to 3% for extruded rod, bar, shapes and tube, 0.5% to 3% for drawn tube) and then artificially overaged in order to achieve the best stress corrosion resistance. The products receive no further straightening after stretching, except that minor straightening is allowed after stretching to comply with standard tolerances.
- T76511 - Solution heat-treated, stress-relieved by controlled stretching and then artificially overaged in order to achieve a good exfoli-ation corrosion resistance. The products receive no further straightening after stretching , except that minor straightening is allowed after stretching to comply with standard tolerances.
