Aluminum Plate 2024-T351 offers an excellent strength-to-weight ratio, high fatigue resistance, and average machinability. The addition of copper to this alloy makes 2024 one of the strongest aluminum alloys, but it also is more succeptible to corrosion than most other aluminum alloys. 2024 is typically used in aerospace applications, clock parts, computer parts, hydraulic parts, bolts, valves, nuts, pistons, and gears.

Applications:
Aluminum sheet 2024 is mainly used in aircraft fittings, gears and shafts, fuse parts, meter shafts and gears, missile parts, regulating valve parts, worm gears, keys, aircraft, aerospace and defense applications; bike frames, all terrain vehicle (ATV) sprockets.
2024-T351 Aluminum Plate
2024 sheet has T351 temper, indicating it has been solution heat treated, cold worked, and naturally aged, followed by a minimal stretching to reduce stresses in the material.
2024 T351 aluminum sheet has good fatigue resistance and is specified for many structural applications for aerospace, including structural components, wing tension structure, and shear ribs and webs.
