Alclad Aluminum 2024-T3
Categories: Metal; Nonferrous Metal; Aluminum Alloy; 2000 Series Aluminum Alloy

Material Notes: General 2024 characteristics and uses (from Alcoa): Good machinability and surface finish capabilities. A high strength material of adequate workability. Has largely superseded 2017 for structural applications.

Uses: Aircraft fittings, gears and shafts, bolts, clock parts, computer parts, couplings, fuse parts, hydraulic valve bodies, missile parts, munitions, nuts, pistons, rectifier parts, worm gears, fastening devices, veterinary and orthopedic equipment, structures. Intrinsic corrosion resistance of 2024 is low for an aluminum alloy, so the clad version is used where needed.

Data points with the AA note have been provided by the Aluminum Association, Inc. and are NOT FOR DESIGN.

Composition Notes: Composition for AA 2024 (not Alclad 2024).
Composition information provided by the Aluminum Association and is not for design.

Key Words: UNS A82024; Alclad 2024-T3; Alclad 2024-T3; Al2024-T3
