6005-T1 Aluminum alloy,Aluminum 6005-T1 alloy,E FORU

### **Product Introduction: 6005-T1 Aluminum Alloy** **6005-T1 Aluminum Alloy** refers to the 6005 alloy (a member of the aluminum-magnesium-silicon family) in a specific temper condition known as T1. The "T1" temper denotes that the product has been naturally aged after an elevated temperature shaping process, such as extrusion, without subsequent cold working or artificial aging. This condition offers a unique set of properties, including good formability in the as-fabricated state and the development of strength through natural aging over time. --- ### **1. International Standards** The alloy and temper are recognized under several international standards. * **AA (Aluminum Association, USA):** AA 6005, Temper T1 * **UNS (Unified Numbering System):** UNS A96005 * **EN (European Norm):** EN AW-6005 - T1 * **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, as the temper does not alter it. | 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 strengthening Mg₂Si precipitates. The low levels of impurities like Copper and Chromium contribute to good corrosion resistance. --- ### **3. Physical Properties** The physical properties are inherent to the 6005 alloy and are consistent across tempers. | 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 T1 Specific)** The mechanical properties for the T1 temper are distinct from the more common T5 or T6 tempers. They represent the condition of the material shortly after extrusion and cooling. * **Tensile Strength:** 150 - 190 MPa (22 - 28 ksi) * **Yield Strength (0.2% Offset):** 80 - 120 MPa (12 - 17 ksi) * **Elongation (% in 50mm):** 14% min * **Hardness (Brinell):** ~ 50 HB **Key Takeaway:** The T1 temper is characterized by **lower strength but significantly higher ductility and formability** compared to artificially aged tempers (T5, T6). The strength will increase slightly over several weeks at room temperature due to natural aging. --- ### **5. Product Applications** The 6005-T1 temper is typically an intermediate state. Its applications are based on the need for post-extrusion forming. * **Intermediate for Further Fabrication:** Extruded profiles in the T1 temper are ideal for components that require significant **cold bending, stretching, or other forming operations** after extrusion. The high ductility makes it easier to shape without cracking. * **Components for Subsequent Heat Treatment:** Profiles can be extruded and held in the T1 temper before being solution heat-treated and artificially aged (to a T6 temper) by the fabricator, allowing for complex formed shapes to be fully hardened. * **Specific Applications:** * Pre-formed structural parts for automotive or rail that will be aged later. * Architectural components that require complex bending after extrusion. --- ### **6. Key Characteristics & Advantages** * **High Formability:** The primary advantage of the T1 temper is its excellent ductility, allowing for extensive cold forming and shaping operations that would be difficult or impossible with the stronger, but more brittle, T5 or T6 tempers. * **Natural Aging:** After forming, the component will naturally age at room temperature, gaining some strength over time. * **Good Corrosion Resistance:** Maintains the good atmospheric corrosion resistance characteristic of the Al-Mg-Si family. * **Good Weldability:** Can be readily welded. However, the heat from welding will create a soft heat-affected zone (HAZ) and may alter the natural aging process. * **Cost-Effective for Complex Shapes:** For parts that require both extrusion and significant forming, using T1 can be more economical than trying to form a fully hard T6 temper. In summary, **6005-T1 Aluminum Alloy** is not typically an end-use temper but a **critical processing temper**. It is strategically selected to leverage its superior formability for manufacturing complex components that are either used in a moderately strong state or are destined for further heat treatment to achieve their final high-strength properties.
