2024 aluminum sheet is a high-strength Al-Cu-Mg alloy sheet widely used in aerospace skin, fuselage, and wing structures. With copper as the primary alloying element, it delivers excellent fatigue resistance and one of the highest strength-to-weight ratios among 2xxx series alloys. Linsy Aluminum supplies 2024 sheet in O, T3, T4, T351, and T851 tempers, including Alclad options, with full mill test certificates.

2024 aluminum sheet is a flat-rolled product made from 2024 aluminum alloy, a heat-treatable Al-Cu-Mg alloy. It is one of the most widely used materials in the aerospace industry, particularly for aircraft fuselage skin, wing panels, and structural components. The alloy’s high strength-to-weight ratio and excellent fatigue resistance make it ideal for tension-dominated structures subject to cyclic loading.
2024 sheet is commonly supplied in T3 temper (solution heat-treated, cold worked, naturally aged) for maximum strength, or in O temper for forming operations. Alclad 2024 sheet, which features a pure aluminum cladding metallurgically bonded to both surfaces, is frequently specified for aerospace applications to provide sacrificial corrosion protection.

2024 sheet achieves ultimate tensile strength up to 483 MPa in T3 temper, providing exceptional strength per unit weight. This is critical for aerospace applications where every gram saved translates to improved fuel efficiency and payload capacity.
The alloy exhibits excellent fatigue resistance, particularly in T3 temper. This property is essential for aircraft skin and structural panels subject to pressurization cycles and flight load variations.
For aerospace applications, 2024 sheet is frequently supplied as Alclad — a composite product with pure aluminum cladding on both surfaces. The cladding provides sacrificial corrosion protection while the 2024 core retains its full mechanical strength.
In the O temper, 2024 sheet can be formed, bent, and deep-drawn. After forming, the material is solution heat-treated and aged to achieve T3 or T4 properties. T3 temper sheet has limited formability and should not be severely formed.
2024 has lower corrosion resistance than 6xxx and 7xxx series alloys. Without cladding or protective coating, it is susceptible to pitting and intergranular corrosion in corrosive environments. Anodizing, chromate conversion coating, or Alclad protection is recommended.
2024 aluminum sheet can be further processed to meet specific requirements:
Standard surface finish for aerospace sheet is mill finish or Alclad. For non-aerospace applications, anodizing and powder coating are available.

What is the difference between 2024-T3 and 2024-T4 sheet?
T3 sheet is cold worked (typically 1-5% reduction) after solution heat treatment before natural aging, giving it slightly higher strength. T4 sheet is naturally aged without cold working, providing better ductility and formability.
What is Alclad 2024 sheet?
Alclad 2024 is 2024 aluminum sheet with a thin layer of pure aluminum (typically 1.5-5% of total thickness per side) metallurgically bonded to both surfaces. The cladding provides sacrificial corrosion protection while the core alloy retains its strength.
Can 2024 sheet be welded?
Conventional arc welding is not recommended for 2024 due to solidification cracking. Riveting is the standard joining method for 2024 sheet in aerospace structures.
What thickness range is available?
Sheet thickness ranges from 0.3 to 6.0 mm. For thicker material (above 6.0 mm), 2024 aluminum plate is available as a separate product.
Can 2024 sheet be formed after heat treatment?
Forming in T3 temper is limited and should be done with caution. For extensive forming operations, use O temper sheet and perform heat treatment after forming.
