Aluminum 2024-T8510 CNC Machining

Heat Treatment of Aluminum 2024-T8510

The T8510 designation in Aluminum 2024-T8510 describes a specific series of treatments.

The T8 portion means the material is solution heat-treated, cold worked, and then artificially aged, a process that results in extremely high strength.

The 510 portion signifies that the material has been stress-relieved by stretching. This critical step removes internal stresses created during quenching, providing exceptional dimensional stability and preventing parts from warping during intensive CNC machining. This dual-process creates a strong, stable material ideal for precision aerospace components.
