2034 aluminum is a heat-treatable alloy in the 2xxx series, primarily alloyed with copper (3.8–4.9%) and magnesium (1.2–1.8%). It is designed for applications requiring high strength and good fatigue resistance, particularly in aerospace structures.
2034 shares compositional similarities with 2024 (the most widely used 2xxx aerospace alloy) but features a higher magnesium content, which contributes to improved fatigue performance. Its corrosion resistance is moderate — protective coatings or Alclad are recommended for exposed environments.
Note: 2034 is a less commonly specified alloy than 2024 or 2014. Designers should confirm availability and specification coverage with suppliers before committing to this alloy in new projects.
Round and rectangular bar for aerospace structural components, machined fittings, and fatigue-critical parts. Available in T3, T4, and T351 temper.

Cold-worked and naturally aged. Good balance of strength and formability. Suitable for parts that undergo moderate forming after solution treatment.
Solution heat-treated and naturally aged. Highest tensile strength in the 2034 family. Used for structural components where maximum load capacity is required.
Solution heat-treated, stress-relieved by stretching, then naturally aged. T351 is the preferred temper for thick plate and bar where residual stress must be minimized — essential for precision-machined aerospace parts that require dimensional stability.
| Tempérer | Meilleur pour | Key Advantage |
|---|---|---|
| T3 | Formed parts, moderate-strength fittings | Good formability + reasonable strength |
| T4 | High-load structural components | Maximum tensile strength |
| T351 | Precision-machined aerospace parts | Low residual stress, dimensional stability |
2034 delivers tensile strength of 380–430 MPa while maintaining aluminum’s inherent weight advantage. This makes it suitable for weight-critical aerospace structures.
The elevated magnesium content (1.2–1.8%) compared to 2024 gives 2034 improved fatigue performance under cyclic loading — an important property for aircraft skin and structural ribs.
2034 machines reasonably well in T3/T4 temper but is not as free-cutting as 2011 or 2030. Chip formation is moderate; carbide tooling is recommended for production runs.
Like other high-copper 2xxx alloys, 2034 has moderate corrosion resistance and is susceptible to stress corrosion cracking in T4 temper. Alclad sheet or chemical conversion coatings are recommended for exposed applications.

Learn more about high-strength 2xxx series alloys:
2034 has higher magnesium content (1.2–1.8% vs 2024’s 1.2–1.8% in a similar range) and higher silicon (0.5–1.2% vs 2024’s 0.50 max). These differences contribute to better fatigue resistance but may reduce weldability. 2024 remains more widely specified and more readily available.
No. Like most high-copper 2xxx alloys, 2034 is not recommended for structural welding. Resistance welding may be used for non-critical joints. Mechanical fastening is preferred.
T351 means the material has been solution heat-treated, stress-relieved by controlled stretching (1–3%), then naturally aged. This process minimizes residual stress, which is critical for thick plate and bar used in precision-machined aerospace parts.
For applications exposed to moisture or salt environments, Alclad (a thin pure-aluminum surface layer) is recommended. For interior or coated structures, bare 2034 with conversion coating may be sufficient.
