AMS4450: Aluminum Alloy, Extruded Profiles (2043-T85) 2.8Cu - 1.65Li - 0.35Mg - 0.1Zr Solution Heat Treated, Stress Relieved by Stretching, and Aged - Material Specification

Features

Issuing Committee: AMS D Nonferrous Alloys Committee

Scope

Content: This specification covers an aluminum alloy in the form of extruded rods, bars, and profiles (shapes) produced with thickness between 0.040 and 2.500 inches (1.02 to 38.10 mm) in thickness, and having a maximum cross sectional area of 23 in² (15000 mm²) and a maximum circumscribing circle diameter (circle size) of 16 inches (406 mm) (see 8.4.1).

Rationale

Content: AMS4450 is a new specification for aluminum extusions for structural aerospace applications requiring low density and high strength and stiffness combined with good corrosion resistance.
