How to Choose the Right 6061 Temper
For maximum formability and bending:
Choose 6061-O. It's soft, easy to shape, ideal for prototypes or deep-drawn components.
For moderate strength with good corrosion resistance:
Choose 6061-T4. Suitable for applications where weight reduction and moderate load-bearing are required.
For high-strength structural applications:
Choose 6061-T6. Perfect for aerospace panels, automotive high-strength parts, and industrial machinery.
For precision machining and long plates with minimal distortion:
Choose 6061-T651. Stress-relieved temper reduces residual stress, ideal for large aerospace and marine components.
For stabilized applications requiring minimal distortion over time:
Choose 6061-T62. Recommended for critical structural components where dimensional stability is crucial.
For aerospace-certified projects:
Choose 6061-T6511. Certified temper for high-reliability aerospace parts, ensuring consistent mechanical properties.
