5 1/4 inch Aluminum Round Bar 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 susceptible 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.

This aluminum round bar is available in multiple lengths ranging from 12 inches up to 144 inches, allowing you to choose the size that best fits your project requirements.

Yes, the 2024 alloy offers excellent strength-to-weight ratio and high fatigue resistance, making it ideal for aerospace components, hydraulic parts, bolts, valves, and gears.

Yes, Material Test Reports (MTRs) are available for this product to verify its chemical and mechanical properties.

The 2024-T351 aluminum round bar has an average machinability rating of 70, making it suitable for various machining processes.

While 2024 aluminum is one of the strongest alloys due to its copper content, it is more susceptible to corrosion compared to other aluminum alloys, so additional corrosion protection may be necessary depending on the application.
