### **Product Introduction: 6005A Aluminum Alloy** **6005A Aluminum Alloy** is a medium-strength, heat-treatable alloy within the aluminum-magnesium-silicon (Al-Mg-Si) family. It was developed as a European variant with slightly modified chemical limits compared to the standard 6005, resulting in enhanced mechanical properties, particularly strength and fracture toughness. It is renowned for its excellent extrudability, making it a premier choice for complex, thin-walled, and structural profiles that require a high strength-to-weight ratio, good corrosion resistance, and superior surface finish for anodizing. --- ### **1. International Standards** 6005A Aluminum Alloy is specified under the following key international standards: * **AA (Aluminum Association, USA):** AA 6005A * **UNS (Unified Numbering System):** UNS A96005 * **ISO (International Organization for Standardization):** ISO 6005A * **EN (European Norm):** EN AW-6005A * **ASTM (American Society for Testing and Materials):** ASTM B221, B241 * **AMS (Aerospace Material Specification):** AMS 4344 --- ### **2. Chemical Composition** The chemical composition limits (in weight percentage) as per the EN 573-3 standard are detailed below. The key difference from standard 6005 is a higher allowable limit for Chromium (Cr) and Manganese (Mn). | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | Balance | | **Silicon (Si)** | 0.50 - 0.9 | | **Magnesium (Mg)** | 0.40 - 0.7 | | **Manganese (Mn)** | ≤ 0.50 | | **Iron (Fe)** | ≤ 0.35 | | **Chromium (Cr)** | ≤ 0.30 | | **Copper (Cu)** | ≤ 0.30 | | **Zinc (Zn)** | ≤ 0.20 | | **Titanium (Ti)** | ≤ 0.10 | | **Others (each)** | ≤ 0.05 | | **Others (total)** | ≤ 0.15 | **Key Takeaway:** The balanced ratio of Silicon and Magnesium ensures the formation of sufficient Mg₂Si for effective precipitation hardening. The controlled addition of Manganese and Chromium increases strength and helps control grain structure. --- ### **3. Physical Properties** The typical physical properties of 6005A aluminum alloy are listed in the table below. | Property | Metric Value | Imperial Value | | :--- | :--- | :--- | | **Density** | 2.70 g/cm³ | 0.0975 lb/in³ | | **Melting Range** | ~ 605 - 655 °C | ~ 1120 - 1210 °F | | **Coefficient of Thermal Expansion** | 23.4 x 10⁻⁶/°C (20-100°C) | 13.0 x 10⁻⁶/°F (68-212°F) | | **Thermal Conductivity** | 180 - 200 W/m·K | 1040 - 1160 BTU·in/(hr·ft²·°F) | | **Electrical Conductivity** | ~ 47-52% IACS | ~ 47-52% IACS | | **Modulus of Elasticity** | 69 - 71 GPa | 10,000 - 10,300 ksi | --- ### **4. Mechanical Properties** Mechanical properties are highly dependent on the temper condition. The following are typical minimum values for extruded sections. **Temper: T5** (Cooled from an elevated temperature shaping process and artificially aged) * **Tensile Strength:** 230 - 260 MPa (33 - 38 ksi) * **Yield Strength (0.2% Offset):** 180 - 210 MPa (26 - 30 ksi) * **Elongation (% in 50mm):** 8% **Temper: T6** (Solution heat-treated and artificially aged) * **Tensile Strength:** 270 - 300 MPa (39 - 44 ksi) * **Yield Strength (0.2% Offset):** 240 - 270 MPa (35 - 39 ksi) * **Elongation (% in 50mm):** 8 - 10% --- ### **5. Product Applications** 6005A is predominantly used for extruded profiles, tubes, and rods. Its primary applications are in high-structural-integrity fields: * **Transportation:** * Automotive and bus structural components (space frames, chassis parts) * Railcar body structures, roof beams, and floor sections * Container bodies * **Architecture & Construction:** * High-strength window and curtain wall mullions * Roof structures and bridges * Handrails, balustrades, and scaffolding * **Marine Industry:** * Masts, booms, and other structural components for boats and yachts * **General Engineering:** * High-stress machinery parts * Welded structures * Ladders and work platforms --- ### **6. Key Characteristics & Advantages** * **High Strength-to-Weight Ratio:** Offers mechanical properties comparable to, and in some cases exceeding, 6061-T6, making it ideal for weight-sensitive structural applications. * **Excellent Extrudability:** Can be pushed through dies at high speeds to create very complex and thin-walled profiles, offering significant design flexibility and cost-efficiency. * **Good Corrosion Resistance:** Demonstrates very good resistance to atmospheric corrosion, typical of Al-Mg-Si alloys. * **Superb Surface Finish & Anodizing Response:** Produces high-quality, bright anodized finishes, which is critical for architectural applications. * **Good Weldability and Brazeability:** Can be readily welded using MIG and TIG methods and is suitable for brazing operations. * **Fracture Toughness:** The modified chemistry of 6005A provides better fracture toughness compared to some other 6xxx series alloys, which is vital for safety-critical components in transportation. In summary, **AA 6005A Aluminum Alloy** is a premium, structurally capable material that bridges the gap between standard extrusion alloys like 6063 and high-strength alloys like 6082. Its optimized chemistry makes it a top-tier choice for demanding applications in **transportation and architecture** where strength, light weight, and manufacturability are paramount.
