6061 Aluminum Alloy: Properties, Tempers, and Applications of O, T4, T6, and T651

Explore 6061 aluminum alloy properties, the differences between O, T4, T6, and T651 tempers

Explore 6061 aluminum alloy properties, the differences between O, T4, T6, and T651 tempers, their applications, and how to select the right condition for your engineering and manufacturing needs.
6061 aluminum alloy is one of the most widely used heat-treatable aluminum alloys, valued for its strength, corrosion resistance, machinability, and versatility. It is commonly used in structural components, industrial equipment, transportation, and precision machining.
However, 6061 aluminum does not have the same mechanical properties in every condition. Its temper affects strength, ductility, formability, and dimensional stability. Understanding the differences between 6061-O, T4, T6, and T651 is essential for selecting the right material for a specific application.
