2024 aluminum alloy (UNS A92024, EN AW-2024) is a copper-based, heat-treatable 2000 series aluminum alloy. Originally developed for aircraft structural applications, it is valued for its high tensile strength, excellent fatigue resistance, and good machinability. The alloy contains approximately 4.4% copper, 1.5% magnesium, and 0.6% manganese, which together enable precipitation hardening to achieve strength levels comparable to many steels at a fraction of the weight.
2024 is not recommended for applications requiring high corrosion resistance unless properly protected, as its copper content reduces natural oxide layer integrity. It is typically used in the T3, T4, T351, or T851 temper for structural tube applications, where strength and fatigue performance are the primary design drivers.

2024 aluminum round tube delivers tensile strength levels that can exceed many low-carbon steels while weighing approximately one-third as much. This makes it a preferred material for weight-sensitive structural designs in aerospace, defense, and high-performance engineering.
The T3 and T351 tempers of 2024 exhibit excellent fatigue performance, which is critical for components subjected to cyclic loading such as aircraft fuselage frames, wing skins, and dynamic structural assemblies.
In the T3, T4, and T851 tempers, 2024 responds well to CNC machining, producing fine chip formation and good surface finish. It is considered one of the better machining aluminum alloys among the high-strength grades, though tool wear is higher than for 6061 due to its greater strength.
2024 has relatively poor corrosion resistance compared to 5000 and 6000 series alloys. In most exterior or humid environments, 2024 aluminum round tube should be protected by cladding (alclad 2024), anodizing, or paint systems. For tube applications in corrosive environments, consult our technical team about available surface protection options.
| Industry / Sector | Aplicaciones típicas | Why 2024 Is Used |
|---|---|---|
| Aerospace & Aircraft | Fuselage frames, wing structures, hydraulic tubing, structural stringers | High strength-to-weight ratio, excellent fatigue resistance |
| Defense & Military | Structural chassis, missile components, armored vehicle frames | High strength, good machinability for complex parts |
| Motorsports & Performance Automotive | Chassis tubing, roll cages, suspension components | Lightweight with high yield strength |
| Maquinaria industrial | High-load structural frames, robotic arm linkages | Good fatigue life under cyclic loading |
| Scientific & Research Equipment | Test rig frames, optical mounting structures | Dimensional stability in T851 temper |

Our advantages for 2024 aluminum tube supply include:
What is 2024 aluminum round tube used for?
2024 aluminum round tube is primarily used in aerospace, defense, and high-performance structural applications where high strength-to-weight ratio and fatigue resistance are required. Common uses include aircraft fuselage frames, wing structures, hydraulic tubing, and performance automotive chassis components.
What tempers are available for 2024 aluminum round tube?
Linsy supplies 2024 aluminum round tube in O, T3, T4, T351, and T851 tempers. T3 and T351 are the most common for structural tube applications due to their high strength and fatigue performance.
Can 2024 aluminum round tube be welded?
2024 has limited weldability and is prone to hot cracking during fusion welding. If fabrication requires joining, mechanical methods (bolting, riveting) are recommended. TIG welding with 2319 filler wire may be considered for repairs, but strength in the heat-affected zone will be reduced compared to the base material.
Does 2024 aluminum round tube come with an MTC report?
Yes. Every order from Linsy includes an MTC (Material Test Certificate) report documenting chemical composition and mechanical properties. SGS third-party testing is available on request at additional cost.
What outer diameters are available for 2024 aluminum round tube?
Linsy supplies 2024 aluminum round tube in a wide range of outer diameters. Typical stock and custom sizes cover 6mm to 300mm OD. If you require a size outside this range, please contact our technical team to confirm feasibility.
How does 2024 aluminum tube compare to 6061 tube?
2024 offers significantly higher tensile and yield strength than 6061, making it better for highly loaded structural applications. However, 6061 has better corrosion resistance and weldability. For aerospace and fatigue-critical applications, 2024 is typically preferred; for general structural and welded assemblies, 6061 is often the more practical choice.
What is the typical lead time for custom 2024 aluminum round tube orders?
For stock specifications, Linsy can deliver quickly from inventory. For custom sizes, non-standard tempers, or processed parts, typical lead time is 10–60 days depending on alloy, dimensions, processing requirements, and order complexity.
¿Cuál es la cantidad mínima de pedido (MOQ)?
Linsy supports low-MOQ orders for custom sizes and non-stock alloys. Standard stock items may have different MOQ requirements. Please contact us with your specific requirements for confirmation.
What payment methods are accepted?
We accept T/T, L/C, and other standard international payment methods. Payment terms can be discussed for established long-term cooperation.
Can I request a sample before placing a bulk order?
Yes, sample pieces or small trial orders are available. Sample costs and delivery terms will be quoted separately.
Does Linsy provide certificates for international shipments?
Yes, all necessary shipping and material documents are provided, including commercial invoice, packing list, certificate of origin (if required), and MTC report. SGS test reports are available on request.
