2024 T351 aluminum plate is a high-strength alloy produced through precise processing and heat-treatment steps. In the T351 temper, the material is solution-treated, stretched to relieve internal stress, and then naturally aged. This combination reduces deformation during machining and ensures more stable performance in demanding applications.
Although 2024 alloy delivers excellent strength, its corrosion resistance is weaker than some other aluminum series. For this reason, Alclad 2024 T351 is often applied to enhance surface protection, especially in environments where moisture or chemical exposure is expected. When welding, it is recommended to take additional protective measures to avoid cracks during welding.
With a density of about 2.78 g/cm³, 2024 T351 plate is significantly lighter than many traditional metals, yet it maintains exceptional structural strength. These characteristics make it widely used in aerospace components, high-performance automotive parts, and other fields where strength-to-weight ratio is critical.
Known for its remarkable fatigue resistance, strong mechanical properties, and dependable machinability, 2024 T351 aluminum plate remains one of the go-to materials for aerospace-grade engineering. Whether you’re designing load-bearing structures or precision-machined parts, this alloy can meet your needs.
2024 T351 offers a noticeably higher strength and stiffness compared to standard aluminum alloys or pure aluminum. Its mechanical performance surpasses common 5000 and 6000 series alloys—such as 6061—especially in strength and fatigue resistance. However, this form of aluminum comes with lower corrosion resistance and more limited weldability, which should be considered during material selection.
