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.
