Performance of 6063 aluminum tube
6063 aluminum alloy is a medium-strength extrusion grade with excellent corrosion resistance, high surface finish, and outstanding anodizing characteristics.
It is widely used for hollow extrusions and architectural applications where smooth appearance, weldability, and good mechanical strength are required.
Compared with 6061 alloy, it offers slightly lower strength but better extrudability and surface quality.
| Property | Imperial | Metric |
| Density | 0.0975 lb/in³ | 2.70 g/cm³ |
| Ultimate tensile strength | 27,000 psi | 186 MPa |
| Yield strength | 21,000 psi | 145 MPa |
| Fatigue strength | 10,000 psi | 69 MPa |
| Shear strength | 17,000 psi | 117 MPa |
| Melting range | 1,140 – 1,210 °F | 616 – 654 °C |
Note: Typical values shown above are for 6063-T52 temper and may vary slightly with different heat treatments.

6063 aluminum tube FAQ
6061 aluminum tube vs 6063 aluminum tube
6061 aluminum tube has higher yield strength and hardness, making it suitable for structural and aerospace applications. 6063 aluminum tube offers better corrosion resistance and superior surface finish, making it the preferred choice for architectural and decorative uses.
6063 T5 aluminum tube vs 6063 T6 aluminum tube
6063 T6 aluminum tube has higher hardness and mechanical strength compared to 6063 T5. However, T6 may be more brittle during processing, while T5 provides a good balance of strength, formability, and anodizing quality, sufficient for most projects.
Can 6063 aluminum tube be bent?
Yes. Thanks to its formability, high strength-to-weight ratio, and excellent corrosion resistance, 6063 aluminum tube can be bent into various shapes. It is widely used in railing systems, frames, and other architectural or industrial applications requiring bending.
How much does 6063 aluminum tube cost?
The price of 6063 aluminum tube is generally calculated per kilogram or per pound and varies with tube size, temper, and surface treatment. Please contact us for an instant quote.
Do you offer large diameter 6063 aluminum tubes?
Yes, Chalco can produce and stock large diameter 6063 aluminum tubes with outer diameters up to 500 mm (20 inch) and customized wall thickness options.
We support both seamless and extruded production methods, depending on the structural requirements. Large diameter tubes are widely used in marine projects, light poles, industrial pipe systems, and architectural structures.
