6061 T6 vs T651 Aluminum (Key Differences)
6061 is a heat-treatable Al-Mg-Si alloy strengthened through solution heat treatment and artificial aging.
T6: Maximum strength, suitable for general structural use
T651: T6 + stress-relieved → reduced internal stress, improved dimensional stability
For CNC machining:
T651 offers better flatness and minimizes deformation during and after machining, making it the preferred choice for precision parts and thick plates.
