### **5025 Aluminum Alloy - Product Datasheet** **Overview** 5025 Aluminum Alloy is a non-heat-treatable aluminum-magnesium (Al-Mg) alloy known for its excellent corrosion resistance, good formability, and high strength-to-weight ratio. As a member of the 5xxx series, it is primarily strengthened by its magnesium (Mg) content. A key characteristic of 5025 is its higher magnesium content compared to some other common 5xxx alloys, which gives it moderate to high strength in the strain-hardened tempers. It is widely used in marine, automotive, and general engineering applications where welding, forming, and durability are required. --- #### **1. Chemical Composition (Weight %)** The typical chemical composition of 5025 Aluminum Alloy conforms to the following international standards: | Element | Min (%) | Max (%) | | :--- | :--- | :--- | | **Silicon (Si)** | - | 0.40 | | **Iron (Fe)** | - | 0.40 | | **Copper (Cu)** | - | 0.10 | | **Manganese (Mn)** | 0.50 | 1.0 | | **Magnesium (Mg)** | 4.50 | 5.50 | | **Chromium (Cr)** | 0.05 | 0.25 | | **Zinc (Zn)** | - | 0.20 | | **Titanium (Ti)** | - | 0.10 | | **Other Elements (Each)** | - | 0.05 | | **Other Elements (Total)** | - | 0.15 | | **Aluminum (Al)** | Balance | Balance | *Note: The exact limits may vary slightly depending on the specific international standard and product form.* --- #### **2. Physical Properties** | Property | Value / Description | | :--- | :--- | | **Density** | ≈ 2.66 g/cm³ (0.096 lb/in³) | | **Melting Range** | ≈ 570 - 640 °C (1058 - 1184 °F) | | **Electrical Conductivity** | ≈ 30-35% IACS (International Annealed Copper Standard) | | **Thermal Conductivity** | ≈ 117 W/m·K | | **Coefficient of Thermal Expansion** | ≈ 23.9 x 10⁻⁶/°C (20-100°C) | | **Modulus of Elasticity** | ≈ 70 GPa (10,200 ksi) | --- #### **3. Mechanical Properties (Typical Values)** Properties vary significantly with temper (condition). The following are typical ranges for common tempers: | Temper | Tensile Strength (MPa) | Yield Strength (0.2% Offset, MPa) | Elongation (% in 50mm) | | :--- | :--- | :--- | :--- | | **O (Annealed)** | 250 - 300 | 120 - 150 | ≥ 20 | | **H12 / H22** | 270 - 320 | 180 - 220 | ≥ 12 | | **H14 / H24** | 290 - 340 | 210 - 250 | ≥ 10 | | **H16 / H26** | 310 - 360 | 240 - 280 | ≥ 8 | | **H18 / H28** | 330 - 380 | 270 - 310 | ≥ 6 | | **H32 / H34 / H36 / H38** | *Similar to H2x series, but with improved stability and flatness.* | *Explanation of Tempers:* * **O (Annealed):** Softest state, maximum ductility. * **H1x:** Strain-hardened only. * **H2x:** Strain-hardened and partially annealed (to a stable condition). * **H3x:** Strain-hardened and stabilized by a low-temperature thermal treatment to improve ductility and resistance to age-softening. --- #### **4. Key Characteristics & Advantages** * **Excellent Corrosion Resistance:** Demonstrates outstanding resistance to atmospheric and saltwater corrosion, making it a prime choice for marine applications. It is highly resistant to chemical attack and industrial environments. * **Moderate to High Strength:** The high magnesium content provides good strength, which can be further enhanced through strain hardening (work hardening). * **Good Formability:** It can be easily formed and shaped in the softer "O" temper. More forming force is required in harder tempers. * **High Weldability:** It can be readily welded using all common techniques, including MIG (Metal Inert Gas) and TIG (Tungsten Inert Gas), without a significant loss of corrosion resistance in the weld zone. * **Good Machinability:** In the strain-hardened tempers (e.g., H3x), it offers fair to good machinability. * **Non-Heat-Treatable:** Its strength is derived solely from work hardening (strain hardening). --- #### **5. Product Applications** 5025 Aluminum Alloy is specified in a wide range of industries due to its versatile properties: * **Marine Industry:** Boat hulls, decks, superstructures, railings, and other components exposed to seawater. * **Transportation:** Body panels, truck and trailer bodies, flooring, and structural components for railway cars. * **Pressure Vessels & Tanks:** Used for storing liquefied gases, chemicals, and other media due to its strength and corrosion resistance. * **General Engineering:** Structural components, crane booms, and military bridges. * **Architecture & Construction:** Used in roofing, wall cladding, and architectural trim where a combination of strength and corrosion resistance is needed. --- #### **6. International Standards** 5025 Aluminum Alloy is recognized under several key international standards: | Standard Organization | Standard Designation | | :--- | :--- | | **ISO** | **AlMg5** (ISO 209) | | **EN (European Norm)** | **EN AW-5025** (EN 573-3) | | **ASTM (USA)** | **ASTM B209** (for Sheet and Plate) | | **AA (Aluminum Association)** | **5025** | *Note: It is crucial to verify the exact grade and specification with material suppliers, as standards and availability may differ by region and product form.* --- **Disclaimer:** The information provided herein is for reference purposes only.
