Machining Characteristics of 2024 Aerospace Aluminum Sheet Plate
When machining 2024 aluminum alloy, it is important to consider its work hardening characteristics, typically using cold working or hot working methods. Caution is needed during welding, as this alloy has relatively poor weldability, which may lead to a reduction in the strength of the welded joints.
2024 aluminum also has high strength and some heat resistance, making it suitable for working parts below 150°C. Its strength exceeds that of 7075 aluminum plates at temperatures above 125°C. It exhibits good formability in the solution-treated, annealed, and freshly quenched states, with significant strengthening effects from heat treatment, although the heat treatment process has strict requirements.
