Different Tempers of 6061 Aluminum Sheet Metal

6061 aluminum alloy is a commonly used aluminum alloy that can be used to manufacture a variety of products, including sheet metal products. It can be processed in different states to obtain different mechanical properties and uses. The following are several common states of 6061 aluminum sheet metal:

T6 6061 Aluminum Sheet: This is one of the most common states in 6061 aluminum sheet metal. In the T6 state, the aluminum alloy undergoes high-temperature solution treatment and then is rapidly quenched. This process gives it high strength and hardness. 6061 aluminum in T6 temper is commonly used in structural applications where strength is critical.

T4 6061 Aluminum Sheet: In this state, the aluminum alloy has been solid solution treated and then aged naturally. It offers good formability and weldability while still possessing reasonable strength. 6061 aluminum in T4 temper is typically used in applications that require forming or bending.

T651 6061 Aluminum Sheet: Similar to the T6 condition, but with additional stretching after solution treatment. This stretching process reduces internal stress and enhances dimensional stability. 6061 aluminum in T651 condition is typically used in applications requiring precision parts and components where tight tolerances are required.

O 6061 Aluminum Sheet: This is the annealed state of 6061 aluminum, completely softened. It has excellent formability but is less strong than in the processed state. 6061 aluminum in the O temper is suitable for applications where extensive forming is required or where strength is not a primary consideration.

T6511 6061 Aluminum Sheet: This is a stretched version of the T651 condition, achieved through a stretching process. It offers properties similar to T651 aluminum, but with improved flatness and straightness. 6061 aluminum in the T6511 temper is typically used in applications where flatness is critical, such as aerospace components.

These are some of the most common states of 6061 aluminum sheets, but there are others available, each offering specific properties suitable for different applications.
