6005C Aluminum alloy,Aluminum 6005C alloy,E FORU

### **Product Introduction: 6005C Aluminum Alloy** **6005C Aluminum Alloy** is a specific variant within the aluminum-magnesium-silicon (Al-Mg-Si) family, recognized primarily in European standards. It is engineered to offer a robust combination of good strength, excellent extrudability, and superior surface quality. While similar to other 6005-series alloys, the 6005C composition is carefully balanced to optimize performance for specific applications, particularly in transportation and architecture, where a reliable combination of mechanical properties, formability, and anodizing response is required. --- ### **1. International Standards** 6005C Aluminum Alloy is primarily defined by European standards. It is less common in the North American AA system. * **EN (European Norm):** EN AW-6005C (EN 573-3) * **ISO (International Organization for Standardization):** Often referenced in ISO standards for specific extruded products. * **Note:** This alloy is typically supplied to meet EN standards or specific technical specifications from industries like automotive (e.g., German DIN standards) or rail (e.g., EN 755 for extruded products). --- ### **2. Chemical Composition** The chemical composition limits (in weight percentage) for EN AW-6005C as per EN 573-3 are detailed below. The key differentiator from other 6005 variants lies in its specific, tightly controlled ranges for Silicon and Magnesium. | 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 (Si) and Magnesium (Mg) ensures the formation of a sufficient amount of the strengthening phase, Magnesium Silicide (Mg₂Si), during heat treatment. The controlled levels of Manganese and Chromium aid in grain structure control without significantly compromising extrudability or corrosion resistance. --- ### **3. Physical Properties** The typical physical properties of 6005C aluminum alloy are consistent with the Al-Mg-Si family. | 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** | 175 - 195 W/m·K | 1010 - 1130 BTU·in/(hr·ft²·°F) | | **Electrical Conductivity** | ~ 46-51% IACS | ~ 46-51% IACS | | **Modulus of Elasticity** | 69 - 71 GPa | 10,000 - 10,300 ksi | --- ### **4. Mechanical Properties** Mechanical properties are dependent on the temper condition. The following are typical values for extruded sections. **Temper: T5** (Cooled from an elevated temperature shaping process and artificially aged) * **Tensile Strength:** 230 - 270 MPa (33 - 39 ksi) * **Yield Strength (0.2% Offset):** 190 - 220 MPa (28 - 32 ksi) * **Elongation (% in 50mm):** 8 - 10% **Temper: T6** (Solution heat-treated and artificially aged) * **Tensile Strength:** 270 - 310 MPa (39 - 45 ksi) * **Yield Strength (0.2% Offset):** 240 - 280 MPa (35 - 41 ksi) * **Elongation (% in 50mm):** 8 - 10% --- ### **5. Product Applications** 6005C is predominantly used for extruded profiles where a consistent and reliable performance is key. Its applications are often found in: * **Transportation:** * Automotive structural components (seat frames, body reinforcements) * Railcar interior structures and non-primary structural components * Truck and container bodywork * **Architecture & Building:** * High-quality window and door frames * Curtain walling mullions and transoms * Handrails, balustrades, and roofing systems * **General Engineering:** * Machinery parts * Welded fabrications * Ladders and work platforms --- ### **6. Key Characteristics & Advantages** * **Excellent Extrudability:** Allows for the production of complex and thin-walled profiles with high surface quality and dimensional accuracy, making it cost-effective for intricate designs. * **Good Strength-to-Weight Ratio:** Provides a reliable level of strength for many structural and semi-structural applications, bridging the gap between 6063 and higher-strength alloys like 6082. * **Superb Surface Finish & Anodizing Response:** Produces excellent, bright anodized finishes, which is a critical requirement for architectural applications where aesthetics are important. * **Good Corrosion Resistance:** Inherits strong resistance to atmospheric corrosion from the Al-Mg-Si family. * **Good Weldability and Brazeability:** Can be readily welded using MIG and TIG methods and is suitable for brazing operations. * **Consistent Performance:** The specific "C" variant is tailored to ensure consistent and predictable behavior during extrusion and subsequent processing. In summary, **EN AW-6005C Aluminum Alloy** is a versatile and highly reliable engineering alloy within the 6005 series. It is optimized for applications that demand a **favorable balance of extrudability, strength, and surface quality**, making it a preferred choice for high-quality architectural systems and general transportation components.
