Aluminum Alloy, Plate 4.4cu 1.5mg 0.60mn (2124-T8151) Solution Heat Treated, Stress Relieved, and Precipitation Heat Treated AMS4221B

This specification covers an aluminum alloy in the form of plate 1.5 inches (38 mm) and over in nominal thickness.

This plate has been used typically for parts requiring a high level of mechanical properties up to 300 degrees F (149 degrees C), but usage is not limited to such applications.

Certain design and fabrication procedures may cause plate to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
