2017 aluminum is a high-strength aluminum alloy that is primarily composed of aluminum with copper as the primary alloying element. It also contains smaller amounts of other elements such as magnesium and manganese to further enhance its mechanical properties. 2017 aluminum offers excellent machinability, good corrosion resistance, and high strength.

2017 aluminum bars are commonly used in applications that require high strength and good machinability, such as aerospace components, structural parts, and machinery components. They are particularly suitable for applications where high load-bearing capabilities and resistance to fatigue are required.

The temper designations for 2017 aluminum bars typically include:

T4: The T4 temper indicates that the aluminum bar has been solution heat treated and naturally aged. It provides a balance between strength and formability.

T6: The T6 temper signifies that the aluminum bar has been solution heat treated and artificially aged. It offers the highest strength and hardness among the common tempers for 2017 aluminum.

T651: This temper represents an artificially aged and stress-relieved condition. It provides high strength, improved dimensional stability, and reduced distortion after machining.
