5154A Aluminum alloy,Aluminum 5154A alloy,E FORU

### **5154A Aluminum Alloy Product Introduction** **Overview** 5154A Aluminum Alloy is a versatile, non-heat-treatable alloy from the Al-Mg series (5xxx series). It is known for its **medium to high strength, excellent corrosion resistance—particularly in marine environments—and good weldability**. As a widely used modification of the standard 5154 alloy, 5154A offers an optimized balance of mechanical properties, formability, and durability, making it a premier choice for welded structures, pressure vessels, and marine applications. --- ### **1. Chemical Composition** The chemical composition of 5154A Aluminum Alloy is carefully controlled to enhance its corrosion resistance and weldability. The following table outlines the typical elemental composition by weight percentage (%). | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | Balance | | **Magnesium (Mg)** | 3.1 - 3.9 | | **Manganese (Mn)** | ≤ 0.50 | | **Silicon (Si)** | ≤ 0.50 | | **Iron (Fe)** | ≤ 0.50 | | **Chromium (Cr)** | 0.15 - 0.35 | | **Copper (Cu)** | ≤ 0.10 | | **Zinc (Zn)** | ≤ 0.20 | | **Titanium (Ti)** | ≤ 0.20 | | **Others (Each)** | ≤ 0.05 | | **Others (Total)** | ≤ 0.15 | *Note: The controlled magnesium content provides a robust combination of strength and resistance to stress corrosion cracking. The low copper content is key to its superior corrosion resistance.* --- ### **2. Physical Properties** The physical properties of 5154A alloy are typical for Al-Mg alloys, contributing to its wide applicability. | Property | Value / Description | | :--- | :--- | | **Density** | 2.66 g/cm³ (0.096 lb/in³) | | **Melting Range** | ~ 590 - 650 °C (1094 - 1202 °F) | | **Electrical Conductivity** | Approximately 32-37% IACS (International Annealed Copper Standard) | | **Thermal Conductivity** | 125 - 140 W/m·K | | **Coefficient of Thermal Expansion** | 23.9 x 10⁻⁶/°C (20-100°C) | | **Modulus of Elasticity** | 70 GPa (10,200 ksi) | | **Corrosion Resistance** | Excellent. Demonstrates outstanding resistance to saltwater corrosion, making it a classic "marine-grade" alloy. | --- ### **3. Mechanical Properties (Typical)** Mechanical properties are enhanced through various strain-hardened tempers. The H32 and H34 tempers are most common. | Temper | Tensile Strength (MPa) | Yield Strength (0.2% Offset, MPa) | Elongation (%) | | :--- | :--- | :--- | :--- | | **O (Annealed)** | ~ 240 - 290 | ~ 100 - 150 | ≥ 18 | | **H32** | ~ 290 - 340 | ~ 210 - 260 | ≥ 10 | | **H34** | ~ 310 - 360 | ~ 230 - 280 | ≥ 8 | | **H36** | ~ 330 - 380 | ~ 250 - 300 | ≥ 6 | | **H38** | ~ 350 - 400 | ~ 270 - 320 | ≥ 5 | *Note: Properties are typical for sheet and plate products and can vary based on product form and exact processing history. The H11x tempers (e.g., H116) are common for plate products used in marine applications.* --- ### **4. Product Applications** 5154A Aluminum Alloy is extensively used in demanding applications where corrosion resistance and weldability are critical. * **Marine & Shipbuilding:** Hulls, superstructures, decks, gunwales, and other critical components for boats and ships. * **Pressure Vessels & Tanks:** Cryogenic tanks, chemical transport tanks, and welded pressure vessels. * **Transportation:** Automotive body panels, truck and trailer bodies, and railcar components. * **Engineering Structures:** Welded frameworks, platforms, and bridges in corrosive environments. * **Consumer Goods:** High-performance bicycle frames and fishing reels. --- ### **5. International Standards** 5154A Aluminum Alloy is recognized under several key international standards, particularly in Europe. | Standard | Designation | Notes | | :--- | :--- | :--- | | **EN** | **EN AW-5154A** (AlMg3.5) | The standard and most common European Norm (EN) designation. | | **ISO** | **AlMg3** (EN 573-3) | A common European designation for this alloy type. | | **AA** | **5154** | The Aluminum Association (AA) designation is the base **5154** alloy, with 5154A being a closely related European variant. | | **ASTM** | **B209, B210, B211** | Standard specifications for Aluminum-Alloy Sheet, Plate, Drawn Pipe, and Bar. 5154A properties are often comparable to 5154 under these standards. | --- ### **Summary of Key Advantages** * **Excellent Marine Corrosion Resistance:** Superior performance in saltwater environments, with good resistance to stress corrosion cracking. * **Good Weldability:** Can be easily welded using common techniques like MIG and TIG without significant loss of properties in the weld zone. * **Medium-High Strength:** Offers a great balance of strength and formability, stronger than 5052 but more formable than 5086/5083 in some tempers. * **Good Formability:** Can be readily formed and machined in the annealed (O) and softer tempers. * **Proven Reliability:** A well-established and trusted material for critical applications in marine and transportation industries. 5154A Aluminum Alloy is a robust and reliable "marine-grade" material, offering an optimal combination of performance and manufacturability.
