Seamless T3 T4 O 2024 Aluminum Tube Cold Drawn
Cold drawn seamless 2024 aluminum tubes (T3 / T4 / O temper) feature aerospace-grade strength, outstanding fatigue resistance, and precise dimensional control, making them ideal for aerospace, defense, and high-performance engineering applications.
As a professional 2024 aluminum tube supplier, Shenzhen Chinalcometal offers a full range of 2024 aluminum round, square, and rectangular tubes that meet AMS quality standards.
2024 aluminum tube forms
Round Tube – for aircraft hydraulic systems, fuel delivery, and instrumentation lines.
Square Tube – for structural frameworks, brackets, and mechanical assemblies.
Rectangular Tube – for confined structural areas requiring high strength and rigidity such as wing spars and racing components.
2024 aluminum tempers
2024-O (Annealed) – high ductility, suitable for forming.
2024-T3 – solution heat-treated, cold worked, and naturally aged; highest strength.
2024-T4 – solution heat-treated and naturally aged; better formability than T3.
2024-T351 / T3511 – stress-relieved variants for thick-wall or complex components.
