5023 Aluminum alloy,Aluminum 5023 alloy,E FORU

### **5023 Aluminum Alloy - Product Introduction** **Overview** 5023 Aluminum Alloy is a non-heat-treatable aluminum-magnesium (Al-Mg) alloy, renowned for its excellent corrosion resistance, particularly in marine environments. It offers a unique combination of moderate to high strength, good formability, and a brilliant, anodizable finish. As a variant within the 5xxx series, it is primarily strengthened by its magnesium (Mg) content and is designed to provide superior performance where weldability, aesthetics, and durability are critical. --- #### **1. Chemical Composition (Weight %)** The typical chemical composition of 5023 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)** | 0.10 | 0.60 | | **Magnesium (Mg)** | 4.00 | 5.20 | | **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 (e.g., EN, ASTM).* --- #### **2. Physical Properties** | Property | Value / Description | | :--- | :--- | | **Density** | ≈ 2.67 g/cm³ (0.0965 lb/in³) | | **Melting Range** | ≈ 570 - 640 °C (1058 - 1184 °F) | | **Electrical Conductivity** | ≈ 35-40% IACS (International Annealed Copper Standard) | | **Thermal Conductivity** | ≈ 125 W/m·K | | **Coefficient of Thermal Expansion** | ≈ 23.9 x 10⁻⁶/°C (20-100°C) | | **Modulus of Elasticity** | ≈ 70 GPa (10,000 ksi) | --- #### **3. Mechanical Properties (Typical Values)** Properties can vary with temper (condition). The following are typical for common tempers: | Temper | Tensile Strength (MPa) | Yield Strength (0.2% Offset, MPa) | Elongation (% in 50mm) | | :--- | :--- | :--- | :--- | | **O (Annealed)** | 230 - 280 | 100 - 130 | ≥ 20 | | **H12 / H22** | 240 - 290 | 160 - 200 | ≥ 12 | | **H14 / H24** | 260 - 310 | 190 - 230 | ≥ 10 | | **H16 / H26** | 280 - 330 | 220 - 260 | ≥ 8 | | **H18 / H28** | 300 - 350 | 250 - 290 | ≥ 5 | | **H32 / H34 / H36 / H38** | *Similar to H2x series, but with improved control of flatness.* | *H1x: Strain-hardened only. H2x: Strain-hardened and partially annealed. H3x: Strain-hardened and stabilized.* --- #### **4. Key Characteristics & Advantages** * **Excellent Corrosion Resistance:** Demonstrates outstanding resistance to atmospheric and saltwater corrosion, making it a premier choice for marine applications. * **Good Strength-to-Weight Ratio:** Offers moderate to high strength while remaining lightweight. * **Superb Formability:** Easily formed and shaped in various tempers, especially in the softer "O" condition. * **High Weldability:** Can be readily welded using common techniques such as MIG and TIG without a significant loss of corrosion resistance in the weld zone. * **Brilliant Surface Finish:** Produces a bright, reflective surface that is highly suitable for anodizing and painting, ideal for architectural and decorative applications. * **Non-Heat Treatable:** Its strength is derived from work hardening (strain hardening), not heat treatment. --- #### **5. Product Applications** 5023 Aluminum Alloy is specified in a wide range of industries due to its versatile properties: * **Marine Industry:** Boat hulls, superstructures, decks, railings, and other components exposed to seawater. * **Architecture & Construction:** Roofing and wall cladding, facades, window frames, doors, and decorative trims. * **Transportation:** Body panels and interior components for trucks, trailers, and railway cars. * **Consumer Durables:** Appliance casings, kitchenware, and furniture. * **General Engineering:** Pressure vessels, chemical tanks, and structural components requiring good corrosion resistance. --- #### **6. International Standards** 5023 Aluminum Alloy is recognized under several key international standards: | Standard Organization | Standard Designation | | :--- | :--- | | **ISO** | **AlMg4.5Mn0.7** (ISO 209) | | **EN (European Norm)** | **EN AW-5023** (EN 573-3) | | **ASTM (USA)** | **ASTM B928** (for plate and sheet) | | **AA (Aluminum Association)** | **5023** | *Note: It is crucial to verify the exact grade and specification with material suppliers, as designations can differ slightly between standards (e.g., EN AW-5049 is very similar and often used interchangeably in some markets).* --- **Disclaimer:** The information provided herein is for reference purposes only.
