Form:

This specification covers an aluminum alloy in the form of extruded wide panel profiles (shapes) and rod and bars produced with cross sectional area of 14 to 30 square inches (90 to 194 square cm) from circumscribing circle diameters (See 8.3) of 14 to 22 inches (356 to 559 mm).

For product with circumscribing circle diameters (See 8.3) 10 inches (254 mm) and under, use AMS 4345.

Application:

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