SAE AMS 4328B: 2019 / Aluminum Alloy, Plate (2397-T87) 2.8Cu - 1.4Li - 0.30Mn - 0.12Zr - 0.10Zn Solution Heat Treated, Cold Worked, and Artificially Aged

Heat Treatments

  • Solution heat treated at 516 to 527°C (960 to 980°F); stretched to produce a nominal permanent set of 2.75% but not less than 1.5% nor more than 4%; artificially aged at 160°C (320°F) for 59 to 61 hours, to the T87 temper.
  • Annealing: Soak for 2 to 3 hours at 404°C (760°F); cool at rate of 28°C (50°F) per hour or slower to 260°C (500°F ); further cooling rate optional. <br />Solution heat treating temperature (for plate): 516-527°C (960- 980°F) , followed by an air cool and quenched.
