Aluminum 2024-T3/T4/351/351/851 Product Guide
Overview
Copper is the main alloying ingredient in 2024 aluminum. It is very strong compared to most aluminum alloys, and has average machinability, but the copper component of this alloy makes it susceptible to corrosion. Many items in this alloy are produced with a clad surface to protect the underlying material. In addition, 2024 is not considered to be weldable.
Finally, the fatigue resistance of 2024 make it a primary choice when the application is expected to be under stress or strain for prolonged periods. It is typically used in aerospace applications, bolts, clock parts, computer parts, hydraulic valve parts, nuts, pistons, and gears. If you need durable and strong aluminum material, this is an excellent choice.
