Strength of 7075 Aluminum Round Bar: T6 and T651 Tempers

7075 aluminium is renowned for its exceptional strength and excellent mechanical properties, making it one of the most commonly used aluminium alloys in industries such as aerospace, automotive, marine, and defence. This high-strength alloy is primarily composed of aluminium, zinc (5.1-6.1%), magnesium (2.1-2.9%), and copper (1.2-2.0%), with trace elements that enhance its performance.

7075-T6:

• Heat Treatment Process: The T6 temper involves solution heat treatment followed by artificial ageing. The alloy is heated to about 450°C, rapidly quenched in water, and then aged at 120°C.
• Mechanical Properties: This temper provides impressive mechanical properties, including a tensile strength of approximately 572 MPa and a yield strength of around 503 MPa. The hardness is about 150 Brinell, making it ideal for applications requiring high strength and resistance to fatigue.
• Applications: T6 tempered 7075 aluminium is used in high-stress components like aircraft structural parts, marine equipment, and high-performance automotive parts.

• Stress-Relieved Temper: The T651 temper is a variant of the T6 temper but includes a stress-relief process. After solution heat treatment and quenching, the material undergoes controlled stretching to relieve internal stresses, then artificially aged.
• Mechanical Properties: T651's properties are similar to T6's, but the stress-relief process ensures improved dimensional stability and reduced risk of warping during machining.
• Applications: Ideal for precision machining and applications where maintaining tight tolerances and dimensional accuracy is crucial.
