### **2034 Aluminum Alloy - Technical Data Sheet** **Overview** 2034 Aluminum Alloy is a high-strength, heat-treatable aluminum-copper alloy primarily developed for aerospace applications. It belongs to the 2xxx series (Al-Cu) of aluminum alloys, which are renowned for their excellent strength-to-weight ratio and good fatigue resistance. While not as commonly referenced as some other 2xxx series alloys like 2024 or 2014, 2034 is engineered for specific high-performance requirements where superior strength is critical. **Key Characteristics** * **High Strength:** Achieves very high mechanical properties after heat treatment (solution heat treatment and aging). * **Good Fatigue Resistance:** Suitable for cyclic loading applications. * **Excellent Machinability:** In the heat-treated temper, it machines to a good surface finish. * **Average Corrosion Resistance:** Like most copper-rich aluminum alloys, its corrosion resistance is lower than that of non-heat-treatable alloys (e.g., 1xxx, 3xxx, or 5xxx series). It often requires alclad coating or other protective finishes for severe environments. * **Weldability:** Fair, but generally not recommended for fusion welding due to a tendency for hot cracking. Resistance welding is typically preferred. --- #### **1. Chemical Composition (Weight %)** The composition conforms to standards such as ASTM B209 and AMS. The following is a typical range: | Element | Content (%) | | :--------------- | :----------------------- | | **Aluminum (Al)** | Balance | | **Copper (Cu)** | 4.0 - 5.0 | | **Manganese (Mn)**| 0.4 - 1.0 | | **Magnesium (Mg)**| 0.4 - 1.0 | | **Silicon (Si)** | ≤ 0.10 | | **Iron (Fe)** | ≤ 0.15 | | **Zinc (Zn)** | ≤ 0.25 | | **Titanium (Ti)** | ≤ 0.10 | | **Other Impurities** | Each: ≤ 0.05, Total: ≤ 0.15 | *Note: The precise limits may vary slightly depending on the specific international standard and product form.* --- #### **2. Physical Properties** | Property | Value / Description | | :-------------------------- | :--------------------------------------------------- | | **Density** | 2.78 g/cm³ (0.100 lb/in³) | | **Melting Range** | ~ 510 - 640 °C (950 - 1185 °F) | | **Electrical Conductivity** | Approximately 30-40% IACS (International Annealed Copper Standard) | | **Thermal Conductivity** | 120 - 150 W/m·K | | **Coefficient of Thermal Expansion** | 23.4 x 10⁻⁶/°C (20-100°C) | | **Modulus of Elasticity (E)** | 73.1 GPa (10.6 x 10⁶ psi) | --- #### **3. Mechanical Properties (Typical)** Properties are highly dependent on the temper condition. | Temper | Tensile Strength (MPa) | Yield Strength (0.2% Offset, MPa) | Elongation (% in 50 mm) | | :----- | :--------------------- | :-------------------------------- | :---------------------- | | **O (Annealed)** | ~ 220 | ~ 95 | ~ 16 | | **T6 / T651** | **~ 510 - 550** | **~ 430 - 470** | **~ 10 - 13** | | **T8 / T851** | **~ 530 - 570** | **~ 470 - 500** | **~ 8 - 11** | *Note: T651/T851 refers to a stress-relieved stretched plate for improved dimensional stability during machining.* --- #### **4. International Standards** 2034 Aluminum Alloy is covered by various international and industry-specific standards, primarily in aerospace. * **ASTM (USA):** * **ASTM B209:** Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate. * **AMS (Aerospace Material Specification - USA):** * **AMS 4209:** Covers Aluminum Alloy 2034 Plate and Sheet. * **European Standards (EN):** * It may be covered under **EN 485-2** for chemical composition, but specific designations like **EN AW-2034** are less common. It is often procured against proprietary or customer-specific specifications. --- #### **5. Product Applications** Due to its high strength, 2034 is predominantly used in demanding aerospace and defense applications. Typical uses include: * **Aircraft Structures:** Upper wing skins, fuselage frames, and bulkheads. * **Aerospace Forgings:** Used for critical structural components like landing gear parts and wing attachments. * **Military Vehicles:** Armor plates and structural members. * **High-Strength Components:** Any application where maximizing strength-to-weight is paramount. --- #### **6.
