2024 Aluminum Thick Plate
Within the aluminum alloy family, the aircraft grade aluminium holds a significant position due to its unique composition and excellent overall performance. Especially in the thick plate sector, its flexible thickness options and reliable performance make it a preferred material for industrial manufacturing and construction engineering.
Thickness is the foundation for 2024 aluminium thick plate's adaptability to different applications. Its specifications cover a wide range, meeting diverse needs from light-duty structures to heavy-duty loads. Based on industry standards and practical application requirements, the standard thickness of 2024 aluminum thick plates starts at 6mm, with mainstream specifications ranging from 6.35mm to 101.6mm. Custom-made products can extend to thicknesses up to 850mm.
It is worth noting that there are slight differences in performance between plates of different thicknesses. For example, medium-thin plates (6.3mm-12.5mm) can achieve an elongation of up to 12%, combining strength and ductility.
While ultra-thick plates (over 80mm) show a slight decrease in elongation, they still maintain stable load-bearing capacity, making them suitable for special applications such as high-pressure vessels. This gradient matching of thickness and performance gives 2024 aluminum thick plates exceptional adaptability to various application scenarios.
High strength and controllable corrosion resistance are the core competitive advantages of 2024 aluminum thick plates. As an aluminum-copper-magnesium alloy, it contains 3.8%-4.9% copper and 1.2%-1.8% magnesium. After heat treatment processes such as T351 and T4, its tensile strength can easily exceed 400MPa, reaching a maximum of 470MPa in the T3 state. This strength level allows it to weigh only one-third of steel under the same load requirements, perfectly aligning with the trend towards lightweight construction.
Regarding corrosion resistance, through optimized processes such as surface passivation and coating treatments, 2024 aluminum thick plates can effectively resist corrosion from industrial atmospheres, fresh water, and slightly saline-alkali environments.
The latest biomimetic composite technology developed by the Institute of Metal Research, Chinese Academy of Sciences, further elevates it to a new type of material combining high strength and high corrosion resistance, significantly reducing the corrosion rate in acidic and alkaline environments.
Furthermore, its excellent machinability allows for easy processing of complex materials such as cutting, drilling, and welding, further expanding its application scope.
A wide range of thicknesses and superior performance make 2024 aluminum plates shine in numerous fields. In industrial manufacturing, 6.35mm-25mm thicknesses are widely used in new energy vehicle body structures, engine mounts, and other components. Tesla, Ford, and other automakers use it as a core material for lightweighting, improving body strength while reducing energy consumption.
In aerospace, 12.5mm-50mm thicknesses are commonly used in critical load-bearing structures such as aircraft fuselage frames and wing spars. Their high strength and lightweight advantages directly improve flight safety and economy.
In construction, 6mm-12mm thicknesses, with their good shapeability and weather resistance, are ideal for large stadium curtain walls and decorative components, combining aesthetics and structural stability.
In shipbuilding, 25mm-80mm thicknesses can be used in hull structural components, effectively reducing ship weight and improving resistance to seawater corrosion, meeting the environmental requirements of the International Maritime Organization.
