6061-T6 aluminum tube is one of the most widely used heat-treated aluminum alloy tubes in structural and engineering applications. Known for its excellent strength-to-weight ratio, corrosion resistance, and good machinability, it is a preferred material for industries requiring lightweight yet durable tubing solutions.
GengFei Steel supplies high-quality 6061-T6 aluminum tubes to customers worldwide, supporting projects in aerospace, transportation, construction, marine engineering, and industrial manufacturing.
What Is 6061-T6 Aluminum Tube?
6061 aluminum alloy belongs to the Al-Mg-Si (aluminum-magnesium-silicon) series and can be strengthened through heat treatment. The “T6” temper indicates that the material has been solution heat-treated and artificially aged to achieve maximum strength.
Compared with many other aluminum alloys, 6061-T6 offers an excellent balance of mechanical performance, corrosion resistance, and workability, making it one of the most versatile aluminum tubing materials available.
Chemical Composition of 6061 Aluminum Alloy
| Element | Typical Content (%) |
|---|---|
| Magnesium (Mg) | 0.8 – 1.2 |
| Silicon (Si) | 0.4 – 0.8 |
| Copper (Cu) | 0.15 – 0.40 |
| Chromium (Cr) | 0.04 – 0.35 |
| Iron (Fe) | ≤ 0.70 |
| Aluminum (Al) | Balance |
This composition provides both strength and corrosion resistance while maintaining good formability.
Mechanical Properties (T6 Temper)
| Property | Typical Value |
|---|---|
| Tensile Strength | ≥ 290 MPa |
| Yield Strength | ≥ 240 MPa |
| Elongation | ≥ 8% |
| Hardness | Approx. 95 HB |
| Density | 2.70 g/cm³ |
These properties make 6061-T6 aluminum tube suitable for load-bearing and structural applications.
