About Aluminum

Compare over 20 aluminum alloys to find the right material for you—all with material certificates for traceability.

High-Strength 2024 Aluminum Rods

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.

Certificates with a traceable lot number are available for these products. Download certificates from ORDER HISTORY after your order ships.
