6005-T5 Aluminum alloy,Aluminum 6005-T5 alloy,E FORU

### **Product Introduction: 6005-T5 Aluminum Alloy** **6005-T5 Aluminum Alloy** is a medium-strength, heat-treatable alloy from the aluminum-magnesium-silicon (Al-Mg-Si) family, defined by its specific T5 temper. The "T5" temper indicates that the product has been cooled from an elevated temperature shaping process (like extrusion) and then artificially aged. This process significantly increases its strength without the need for a separate solution heat treatment step. 6005-T5 is renowned for its excellent extrudability, offering a superb balance of strength, corrosion resistance, and surface quality, making it a prime choice for a wide range of structural and architectural applications. --- ### **1. International Standards** The alloy and temper are recognized under several key international standards. * **AA (Aluminum Association, USA):** AA 6005, Temper T5 * **UNS (Unified Numbering System):** UNS A96005 * **EN (European Norm):** EN AW-6005 - T5 * **ISO (International Organization for Standardization):** AlMgSi(C) - T5 * **ASTM (American Society for Testing and Materials):** ASTM B221 (Standard Specification for Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes) --- ### **2. Chemical Composition (Base Alloy 6005)** The chemical composition is that of the base 6005 alloy. | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | Balance | | **Silicon (Si)** | 0.60 - 0.9 | | **Magnesium (Mg)** | 0.40 - 0.6 | | **Manganese (Mn)** | ≤ 0.10 | | **Iron (Fe)** | ≤ 0.35 | | **Chromium (Cr)** | ≤ 0.10 | | **Copper (Cu)** | ≤ 0.10 | | **Zinc (Zn)** | ≤ 0.10 | | **Titanium (Ti)** | ≤ 0.10 | | **Others (each)** | ≤ 0.05 | | **Others (total)** | ≤ 0.15 | **Key Takeaway:** The balanced Mg and Si content allows for the formation of Magnesium Silicide (Mg₂Si), which precipitates during the artificial aging process to provide strength. The low copper content ensures excellent corrosion resistance. --- ### **3. Physical Properties** The physical properties are inherent to the 6005 alloy. | 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 (Temper T5 Specific)** The T5 temper provides a significant increase in strength over the T1 temper while maintaining good ductility. These are typical minimum values for extruded sections. * **Tensile Strength:** 240 - 270 MPa (35 - 39 ksi) * **Yield Strength (0.2% Offset):** 200 - 230 MPa (29 - 33 ksi) * **Elongation (% in 50mm):** 8 - 10% * **Hardness (Brinell):** ~ 80 HB **Key Takeaway:** The T5 temper offers a **favorable strength-to-weight ratio**, making it suitable for many structural applications. It is stronger than 6063-T5 but generally has slightly lower strength and better extrudability than 6061-T6. --- ### **5. Product Applications** 6005-T5 is predominantly used in the form of extruded profiles, tubes, and rods. Its applications are widespread across industries requiring a combination of light weight, strength, and good finish. * **Transportation:** * Automotive and bus structural components (seat frames, roof rails, body moldings) * Railcar interior structures and trim * Truck and container body frames * **Architecture & Construction:** * Window and door frames * Curtain wall mullions and transoms * Handrails, balustrades, and ladders * Roofing and siding systems * **General Engineering & Consumer Goods:** * Machinery and equipment parts * Welded structures * Furniture frames * Sports equipment --- ### **6. Key Characteristics & Advantages** * **Excellent Extrudability:** Can be extruded into complex, thin-walled profiles at high speeds, making it a very cost-effective choice for intricate cross-sections. * **Good Strength-to-Weight Ratio:** Provides substantial mechanical properties for structural applications while maintaining the lightweight nature of aluminum. * **Superb Surface Finish & Anodizing Response:** Produces a high-quality, bright anodized finish, which is critical for architectural applications where aesthetics are paramount. * **Good Corrosion Resistance:** Exhibits very good resistance to atmospheric corrosion, typical of Al-Mg-Si alloys with low copper content. * **Good Weldability:** Can be readily welded using MIG and TIG methods, though the heat from welding will reduce strength in the heat-affected zone (HAZ). * **Economical Production:** The T5 temper is highly efficient for extruders as it utilizes the heat from the extrusion process directly, avoiding a separate solution heat treatment step. In summary, **6005-T5 Aluminum Alloy** is a versatile and highly popular **general-purpose structural alloy**. It hits a sweet spot for extruders and designers, offering a superior blend of **manufacturability, mechanical properties, and surface quality**, making it a first-choice material for a vast range of applications in transportation, architecture, and general engineering.
