1/2 inch Aluminum Square 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 square bar is made from 2024 alloy with a T351 temper and cold finish production method. It offers excellent strength-to-weight ratio, high fatigue resistance, and average machinability. The alloy contains copper, making it one of the strongest aluminum alloys, but it is more susceptible to corrosion than other aluminum alloys.

Yes, the 2024-T351 aluminum square bar is available for custom cutting at the warehouse. Length options range up to a maximum of 144 inches, and various standard cut lengths are offered in stock.

Yes, this alloy is typically used in aerospace applications and for manufacturing clock parts, computer parts, hydraulic parts, bolts, valves, nuts, pistons, and gears due to its high strength and fatigue resistance.

The product complies with RoHS and REACH standards and has ASTM B211, AMS 4120, and AMS QQ-A-225/6 certifications. Additionally, a Material Test Report (MTR) is available upon request.

The square bar is shipped in various lengths with corresponding weights; for example, a 12-inch piece weighs approximately 0.31 lb. All listed lengths are in stock and available for immediate shipment.
