2024 aluminum wire is drawn from the 2024 alloy—a Cu-Mg-Mn strengthened, heat-treatable alloy in the 2xxx series. In wire form it is primarily produced in T3 (cold-worked then naturally aged) and T4 (solution heat-treated then naturally aged) tempers, both delivering high tensile strength and good fatigue performance. The wire is widely used for aerospace rivets and structural fasteners where a high-strength, lightweight fastening solution is required.
Compared to other aluminum wire grades, 2024 offers one of the best strength-to-weight ratios in the 2xxx series. Its Cu content (3.8–4.9 %) gives the alloy strong precipitation-hardening capability, while the Mn and Mg additions improve grain structure and corrosion resistance under specific conditions.

| Tempérer | Résistance à la traction (MPa) | Limite d'élasticité (MPa) | Élongation (%) | Electrical Conductivity (% IACS) |

| T4 | 435 | 280 | 12–18 | 30 |
T3 temper (cold-worked after solution treatment, then naturally aged) provides the highest tensile strength. T4 temper (solution heat-treated, then naturally aged without cold work) offers slightly lower strength but higher elongation. Both tempers are commonly specified for aerospace rivet wire.
Additional temper data (for reference—other tempers may not be standard for wire):
| Tempérer | Résistance à la traction (MPa) | Limite d'élasticité (MPa) | Allongement A50 (%) |
|---|---|---|---|
| O | ≤220 | ≤95 | 12–18 |
| T6 | 430 | 310 | 5–8 |
| T851 | 455 | 350 | 3–5 |
O and T6/T851 values above are typical for sheet/bar products; availability in wire form should be confirmed with the supplier.
T3 is the most common temper for 2024 rivet wire. After solution heat-treatment, the wire is cold-drawn to final diameter and then naturally aged. This process produces the highest tensile strength among the standard wire tempers, making it suitable for aerospace rivets that must carry high shear loads. The cold-work also improves dimensional precision.
T4 wire is solution heat-treated and naturally aged without additional cold work after heat treatment. It offers good strength with higher ductility, which can be advantageous for forming operations or where a slight increase in elongation is needed. T4 is also used when the cold-drawing step after heat treatment is impractical for the required diameter.
With a tensile strength of 470 MPa in T3 temper, 2024 wire provides strength comparable to many steels at roughly one-third the density. This makes it a preferred choice for weight-sensitive aerospace and transportation applications.
The Cu-Mg-Mn strengthening mechanism in 2024 alloy gives it superior fatigue performance compared to non-heat-treatable alloys. This is critical for rivets and fasteners that experience cyclic loading in aircraft structures.
In T3 and T4 tempers, 2024 aluminum has good machinability. It can be readily cut, headed, and formed on precision screw machines, making it suitable for fastener production.
2024 alloy has moderate corrosion resistance in many environments, but it is susceptible to stress corrosion cracking in T3/T4 tempers under certain conditions. For exposed or marine applications, protective coatings, anodizing, or Alclad wire should be considered. Intergranular corrosion can also occur if heat treatment is not properly controlled.
2024-T3/T4 wire is typically supplied as-drawn with a smooth, bright surface. Additional processing options include:
Welding of 2024 wire is not recommended for structural applications without proper heat treatment afterward, as welding destroys the precipitation-hardened structure. Resistance welding (spot welding) may be acceptable for non-critical joints.
Every order of 2024 aluminum wire from Linsy is accompanied by:
Third-party testing reports (e.g., SGS) are available on request. Linsy operates under ISO 9001, ISO 14001, and ISO 45001 management system certifications.
Linsy Aluminum supplies 2024-T3/T4 wire with full MTC documentation and traceability. Key advantages for wire buyers:
Lead time for standard sizes is typically 10–60 days depending on quantity and specification. Custom requirements may require additional production time.
T3 wire is cold-drawn after solution heat treatment, then naturally aged. T4 wire is solution heat-treated and naturally aged without cold work after heat treatment. T3 has higher tensile strength (470 MPa vs 435 MPa) but lower elongation. T4 has slightly lower strength with better ductility.
Standard diameter range is 0.8–30 mm. Custom diameters outside this range may be available upon request.
2024 alloy has moderate corrosion resistance but is not ideal for direct marine exposure without protective coating. For marine rivets, consider Alclad 2024 wire or an alternative alloy such as 5056.
Common standards include ASTM B211 (rod, bar, and wire), AMS 4101 (aerospace material specification), EN 573-3 (chemical composition), and GB/T 3191 (Chinese standard for extruded bars and wire).
Welding of 2024 wire is generally not recommended for structural applications. The heat from welding destroys the precipitation-hardened structure. Resistance spot welding may be acceptable for non-critical joints, but post-weld heat treatment is needed to restore properties.
