Understanding the T4, T6, and T651 Tempering Processes

The temper designation (T4 T6 T651) in 6061 T4 T6 T651 aluminum sheet denotes the specific temper or condition that the alloy is treated to achieve its desired properties and characteristics. The three commonly used tempers are:

• T4: Solution heat-treated and naturally quenched, resulting in increased strength and hardness but reduced ductility.
• T6: Solution heat-treated, then stretched and artificially aged, resulting in increased strength and hardness but increased ductility compared to T4.
• T651: Solution heat-treated, then stretched and artificially aged, followed by an additional artificial aging process to enhance the alloy’s mechanical properties, primarily yield strength.
