High-Strength 2024 Aluminum Bars

Balance high strength and workability. Initially designed for aircraft frames, 2024 aluminum is turned into parts that need to be especially strong, such as couplings for servomotor shafts. It’s one of the most widely used high-strength alloys, made into fasteners, gears, and everything in between. It’s also easier to form and weld than 7075 aluminum, among the strongest aluminum alloys out there.

Cold Drawn—Formed by a die for close-tolerance widths, then cut to the lengths listed.

Tight-Tolerance High-Strength 2024 Aluminum Rods

For the best balance of precision, strength, and workability, choose these 2024 aluminum rods. They’re ground to paper-thin tolerances for parts that require pinpoint precision. Held to a strict straightness tolerance, they're all set to turn in your lathe.

Initially designed for aircraft frames, 2024 is turned into parts that need to be especially strong, such as couplings for servomotor shafts. It’s one of the most widely used high-strength alloys, made into fasteners, gears, and everything in between. It’s also easier to form and weld than 7075 aluminum, among the strongest alloys out there.
