The cold-drawn 2017 T351 aluminum alloy is known for its high strength, good machinability, and fatigue resistance, and is frequently used in areas requiring high durability such as aerospace, automotive, and engineering. Thanks to its copper content, this alloy is well-suited for load-bearing and strength-critical components, providing long-lasting performance, especially in environments with intense vibration and impact. However, the high copper content limits its natural corrosion resistance; therefore, extra protective coating is required for use in open-air or marine environments. Its suitability for anodizing increases surface durability and corrosion resistance.

The weldability of the 2017 T351 aluminum alloy is limited; therefore, mechanical fastening methods are usually preferred in assembly. The cold-drawing process provides good bendability and high formability, even in complex shapes. Its high vibration resistance gives advantages in durability and performance in industries like automotive and aerospace. Advantages include high strength, fatigue resistance, good machinability, and anodizing compatibility, while disadvantages are low natural corrosion resistance and limited weldability. These characteristics make 2017 T351 aluminum alloy an ideal material for projects requiring durability and high performance.
