SAE AMS4336B

This specification covers an aluminum alloy procured in the form of extruded bars, rods, and profiles (shapes) with nominal thickness up to 3.000 inch (76.20 mm), inclusive, and having a cross-sectional area of 12 square inches (77 square centimeters) maximum and circle size of 10 inches (254 mm) maximum (see 8.6).

These extrusions have been used typically for structural applications requiring a combination of high tensile and compressive strength and good exfoliation corrosion resistance, but usage is not limited to such applications.
