SAE AMS 4416A

This specification covers an aluminum-lithium alloy in the form of extruded profiles.These extrusions have been used typically for machined parts requiring dimensional stability during machining processes, and high strength, but usage is not limited to such applications.Certain processing procedures may cause this product to become susceptible to stress-corrosion cracking; ARP823 recommends practices to minimize such conditions.
