Flatness & Stress-Relieved Aluminum Plates (T651)
Why T651 Condition is Critical for Milling
The T651 temper designation indicates that aluminum plates have been solution heat-treated, quenched, and then stress-relieved by stretching. This process removes internal stresses that could cause warping during material removal operations, making it essential for precision CNC machining.
Stress Relief Process
- • Controlled stretching removes residual stresses
- • Eliminates warping during machining
- • Maintains dimensional stability
- • Reduces spring-back after material removal
Machining Benefits
- • Consistent cutting forces
- • Predictable tool life
- • Superior surface finish
- • Reduced scrap rates

Frequently Asked Questions
Common questions about aluminum plates and their applications
6061-T651 is the most popular choice for general CNC milling due to its excellent machinability, good strength-to-weight ratio, and stress-relieved condition. For high-strength applications, 7075-T651 offers superior mechanical properties but requires more careful machining parameters. 5083-H116 is preferred when corrosion resistance is paramount, such as marine or chemical processing applications.
Stress-relief (T651 condition) eliminates internal stresses created during the rolling and heat treatment process. Without stress relief, removing material during machining can cause the plate to warp or bow as internal stresses are released. This is particularly critical for precision components where tight tolerances must be maintained throughout the machining process. The T651 temper ensures dimensional stability and reduces scrap rates.
Our computer-controlled sawing equipment achieves ±0.5mm cutting accuracy across all aluminum plate thicknesses. This precision, combined with our material optimization algorithms, ensures minimal waste while delivering parts ready for immediate machining operations. The cut surfaces maintain excellent edge quality, reducing the need for additional finishing operations.
