The 2017-T451 aluminum alloy belongs to the copper-based (Al-Cu) wrought alloy group and is used in engineering applications that require high strength and dimensional stability. The T451 temper includes solution heat treatment, artificial aging, and stress relieving processes, which reduce internal stresses and minimize the risk of deformation after machining. In terms of mechanical properties, 2017-T451 offers higher yield and tensile strength than the 6061-T6 alloy, while remaining below the very high strength levels provided by the 7075-T6 alloy. When compared with 2024-T3, it falls within similar strength ranges and may exhibit a more balanced machinability performance.

From a corrosion resistance standpoint, 2017-T451 exhibits moderate performance due to its copper content. In this respect, it performs below magnesium-silicon based alloys such as 6061-T6; however, when appropriate surface treatments are applied, it provides sufficient durability for industrial applications. The alloy demonstrates good coatability and is suitable for anodizing, painting, and chemical coating processes. In particular, surface hardness and corrosion resistance can be enhanced through hard anodizing treatments. While its coating behavior is similar to that of 2024-T3, more homogeneous surface results can generally be achieved compared to the 7075-T6 alloy.

Machinability is one of the key advantages of the 2017-T451 alloy. It provides good surface quality during machining operations and exhibits stable behavior in CNC processes; in this regard, it offers better machinability than 6061-T6 and a level comparable to 7075-T6. However, its bending capability is limited, as the high strength of the alloy increases the risk of cracking at small bend radii; therefore, it falls behind 5xxx series aluminum alloys in terms of formability. With respect to vibration response, its rigid structure enables it to limit vibration amplitudes under dynamic loading, thereby supporting structural stability.

In terms of weldability, the 2017-T451 alloy has limited welding capability due to its high copper content. During welding operations, there is a risk of hot cracking and a reduction in mechanical properties in the weld zone; therefore, alloys such as 6061-T6 are generally preferred for applications requiring welded fabrication. The 2017-T451 alloy is most commonly joined using mechanical fastening methods such as riveting and bolting. It is widely used in the aerospace, defense, automotive, machinery, and mold manufacturing industries for load-bearing structural components, fasteners, mold plates, and high-strength mechanical parts.
