2024 O aluminum alloy sheet is a high-strength aerospace-grade material known for its outstanding fatigue resistance and dependable machinability. Engineered for performance in demanding structural environments, it is widely used in aircraft production and other applications that require a superior strength-to-weight ratio.
The 2024 aluminum sheet in O temper is fully annealed and non-heat-treated, offering exceptional formability for stamping, deep drawing, and general sheet-metal fabrication. Although lightweight, it provides solid mechanical performance and maintains good resistance to corrosion—two key reasons it remains a preferred choice in aviation manufacturing.
Containing roughly 3.8–4.9% copper, 2024 alloy belongs to the 2000 series of aluminum alloys and can be strengthened through heat treatment when higher mechanical properties are required. For added surface durability, 2024 o aluminum plates are often supplied with alclad layers or processed through anodizing, improving protection against wear and environmental exposure.
• High Strength:
After annealing, 2024 o aluminum sheet delivers a tensile strength of around 140–210 MPa, giving the metal a noticeable boost in mechanical strength.
• Low Strength-to-Weight Ratio:
Because the alloy contains a high percentage of aluminum along with added copper, its strength-to-weight ratio remains relatively low compared with other structural alloys.
• Excellent Machinability:
In the annealed temper, the material becomes more ductile and easier to work with. It supports a wide range of sheet-metal processes such as deep drawing, stamping, shearing, and bending. It can also be used with Alclad cladding and anodizing for additional surface protection.
• Strong Fatigue Resistance:
2024 o alclad aluminum sheet offers exceptional resistance to cyclic loading and can endure far more alternating stress cycles than many other aluminum alloys.
