SAE AMS4338 Revision B, April 1, 2018
Aluminum Alloy, Extrusions 4.0Cu - 1.3Mg - 0.60Mn (2026-T3511) Solution
Heat Treated and Stress Relieved by Stretching
Description / Abstract:
Form
This specification covers an aluminum alloy in the form of extruded bars, rods, and profiles (shapes) with a maximum crosssectional area of 25 in2 (161 cm2), a maximum circle size of 12 inches (305 mm) and a nominal thickness up to 3.250 inch (82.54 mm), inclusive.
Application
These extrusions have been used typically for machined parts requiring dimensional stability during machining processes and for parts requiring high strength and damage tolerance, where fabrication does not normally involve welding, 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.
