What is 6061 aluminum T6 temper
6061: Indicates that the alloy belongs to the 6XXX series aluminum alloy. Its main alloying elements are magnesium (Mg) and silicon (Si). It has good mechanical properties and corrosion resistance.
T6: Indicates that the aluminum alloy has undergone a solution heat treatment + artificial aging strengthening process to achieve optimal strength.
- Solution Heat Treatment: The aluminum alloy is heated to about 530°C (985°F) to fully dissolve the alloying elements, and then quickly quenched to room temperature.
- Artificial aging: The quenched aluminum alloy is heated to 160°C (320°F) and maintained for 8 hours to promote the precipitation of alloying elements and form a strengthening phase, thereby increasing hardness and strength.

Why is T6 the most popular temper for 6061 alloy?
Among the various 6061 aluminum alloy tempers, T6 temper has become the first choice in the market due to its excellent comprehensive performance. Whether in terms of strength, processing performance, or fatigue resistance, T6 has shown outstanding advantages. The table below provides a detailed performance comparison to help you better understand the temper advantages of 6061 T6 temper.
| Advantages | General performance of 6061 | Is the 6061-T6 temper optimal? | Explain |
| Strength to Weight Ratio | 6061 has a good strength-to-weight ratio, being stronger than pure aluminum while remaining lightweight. | Best | The maximum strength (tensile strength 310-330 MPa) was achieved after T6 treatment, which was much higher than that of O and T4 tempers. |
| Machinability | 6061 is suitable for CNC machining, turning, drilling, milling and other processes, and has good processing performance. | Best | T6 has moderate hardness and better cutting performance, and is suitable for CNC precision machining. T4 is slightly inferior. |
| Anti-fatigue performance | 6061 has good fatigue resistance and is suitable for situations where long-term load bearing is required. | Best | After T6 treatment, the internal structure of the material is more uniform and its fatigue resistance is better than that of the annealed temper (O temper). |
| Surface treatment compatibility | 6061 can be subjected to surface treatments such as anodizing, electroplating, and spraying to improve aesthetics and durability. | Best | The hardness and structure of T6 temper are suitable for surface treatment such as anodizing, electroplating, and spraying, and the surface wear resistance is better. |
| Corrosion resistance | 6061 has excellent resistance to oxidation and corrosion, making it suitable for marine, outdoor and wet environments. | Best | T6 still maintains the good corrosion resistance of 6061 and is particularly suitable for outdoor or humid environments. |
| High temperature resistance | The performance of 6061 is stable at room temperature and medium temperature, but its strength will decrease at high temperature. | Not optimal | T6 will lose strength in high temperature environments, and T651 or other heat treatments may be more suitable for extreme temperature environments. |
| Weldability | 6061 can be MIG and TIG welded, but the strength after welding will be affected in some heat treatment tempers. | Not optimal | 6061-T6 can be welded, but the strength of the heat affected zone will be reduced after welding, and the welding performance of T4 temper is better. |
- Reasonable production cost: Compared with 7XXX high-strength aluminum alloy, 6061-T6 has lower raw material and processing costs. At the same time, the heat treatment process is mature, suitable for large-scale manufacturing, and cost-effective.
- Adequate supply and high market recognition: Due to the wide application of 6061-T6 and the mature global supply chain, almost all aluminum alloy manufacturers can provide stable supply, convenient procurement, and small price fluctuations, making it the preferred aluminum alloy in the market
Therefore, 6061-T6 is not only the alloy of choice in many industries, but also an indispensable and important material in modern industrial manufacturing.

More 6061 aluminum temper selection tips
When choosing 6061 products, T6 temper is the most common strengthening temper, but it is not the only choice. Different tempers are suitable for different processing needs, so understanding the difference between T6 and other tempers, as well as the processing methods suitable for T6 temper, can help you choose the right aluminum bar products more accurately.
| temper | Features | Strength (MPa) | Application Scenario |
| 6061-O | Annealed temper, very soft | 124 MPa | Deep drawing, bending, applications requiring high ductility |
| 6061-T4 | Solution treated but not fully aged, lower strength | 207 MPa | Applications requiring subsequent processing or forming |
| 6061-T6 | Solution treatment + artificial aging, highest strength | 310-330 MPa | Structural parts, mechanical parts, large projects |
| 6061-T651 | Tensile stress relieved version in T6 temper | 310-330 MPa | High-precision machining to reduce internal stress and deformation |
Selection suggestion:
- If high-strength and good rigidity materials are required, T6 is the first choice, especially for structural parts that bear heavy loads.
- If the material requires better plasticity, such as bending, stamping or stretching, it is recommended to choose O temper or T4 temper.
- If used for CNC precision machining, T651 is better because it is stress-relieved and less likely to deform.
