1050-O Aluminum Tube Overview for High-Formability Applications
When projects demand maximum ductility, excellent corrosion resistance, and reliable conductivity rather than high strength, 1050-O aluminum tube is an ideal choice. As a professional aluminum supplier, GNEE offers stable-quality 1050-O aluminum tubes and related products to support a wide range of industrial and commercial applications. Reach out to GNEE today to explore material options tailored to your forming and fabrication requirements.
What Is 1050-O Aluminum Tube?
1050-O aluminum tube is produced from commercially pure aluminum with a minimum aluminum content of 99.5%. It belongs to the 1xxx series of aluminum alloys and is supplied in the fully annealed "O" temper. This temper condition provides the lowest mechanical strength but the highest ductility, making the alloy exceptionally easy to form, bend, and shape.
Compared with other tempers of 1050 aluminum, 1050-O aluminum tube offers superior softness and plasticity, which makes it especially suitable for deep drawing, spinning, and complex cold-forming processes.
Key Properties of 1050-O Aluminum Tube
-
High Formability of 1050-O Aluminum Tube
1050-O aluminum tube exhibits outstanding formability and can undergo deep drawing, stretching, spinning, and bending without cracking. This makes it well suited for complex shaping operations.
-
Corrosion Resistance of 1050-O Aluminum Tube
Due to its high purity, the 1050-O aluminum tube demonstrates excellent resistance to corrosion in most indoor and outdoor environments, extending service life and reducing maintenance requirements.
-
Electrical and Thermal Conductivity of 1050-O Aluminum Tube
The alloy offers high electrical and thermal conductivity, which supports its use in electrical, electronic, and heat-transfer applications.
-
Low Strength Characteristics of 1050-O Aluminum Tube
As a non-heat-treatable alloy, 1050-O aluminum tube has relatively low mechanical strength and cannot be strengthened by heat treatment.
-
Ductility and Cold Working Performance of 1050-O Aluminum Tube
The fully annealed condition provides excellent ductility, allowing efficient cold working through rolling, stamping, and forming processes.
-
Weldability of 1050-O Aluminum Tube
1050-O aluminum tube offers good weldability and is compatible with TIG, MIG, resistance welding, and gas welding. For welding similar alloys, 1100 filler wire is recommended, while 4043 or 5356 fillers are suitable when joining with other aluminum series.
-
Surface Quality and Reflectivity of 1050-O Aluminum Tube
The alloy has high reflectivity and responds well to surface treatments, making it suitable for decorative components and lighting applications.
-
Machinability Limitations of 1050-O Aluminum Tube
Due to its softness, machinability is relatively limited, and care is required during mechanical processing to avoid deformation.

Processing and Heat Treatment of 1050-O Aluminum Tube
Annealing: Typically heated to 350–430 °C and cooled slowly to improve ductility and relieve internal stress
Heat Treatment: Not applicable, as the alloy is non-heat-treatable
Surface Finishing: Suitable for anodizing, polishing, and chemical brightening
Comparison of 1050-O Aluminum Tube with Other Tempers
Compared with H14 or unannealed tempers, 1050-O aluminum tube offers significantly higher ductility and formability. While H14 provides higher tensile strength through work hardening, it sacrifices plasticity. The O temper delivers more stable performance for complex forming and deep drawing applications.
