2024 Aluminum Alloy, Aluminium AA2024 2024T3, 2024T351, 2024T4

Aluminum 2024 is one of the highest strength 2xxx alloys, the copper and magnesium are the main elements in this alloy. The most commonly used temper designs include 2024T3, 2024T351, 2024T4, 2024 T6 and 2024T4. The corrosion resistance of 2xxx series alloys is not as good as most other aluminum alloys, and intergranular corrosion may occur under certain conditions. Therefore, these sheet alloys are usually clad with high-purity alloys or 6xxx series magnesium-silicon alloys to provide galvanic protection for the core material, thereby greatly improving corrosion resistance.

2024 aluminium alloy is widely used in the aircraft industry, such as aircraft skin sheet, automotive panels, bulletproof armor, and forged and machined parts.

Alclad 2024 aluminum alloy combines the high strength of Al2024 with the corrosion resistance of a commercial pure cladding. Used in truck wheels, many structural aircraft applications, mechanical gears, screw mechanical products, auto parts, cylinders and pistons, fasteners, mechanical parts, ordnance, entertainment equipment, screws and rivets, etc.
