### **Product Introduction: 6006 Aluminum Alloy** **6006 Aluminum Alloy** is a heat-treatable alloy within the aluminum-magnesium-silicon (Al-Mg-Si) family. It is specifically formulated to offer a unique combination of high formability and good strength after heat treatment. While similar to other 6xxx series alloys, 6006 is particularly noted for its excellent bending and roll-forming capabilities, making it a preferred choice for applications requiring complex shapes and a high-quality painted or anodized finish, especially in the automotive and appliance industries. --- ### **1. International Standards** 6006 Aluminum Alloy is recognized under the following international standards: * **AA (Aluminum Association, USA):** AA 6006 * **UNS (Unified Numbering System):** UNS A96006 * **ISO (International Organization for Standardization):** AlMgSi * **EN (European Norm):** EN AW-6006 --- ### **2. Chemical Composition** The chemical composition limits (in weight percentage) as per the AA standard are detailed below. Its composition is balanced to enhance formability while retaining the ability to be strengthened by precipitation hardening. | Element | Content (%) | | :--- | :--- | | **Aluminum (Al)** | Balance | | **Silicon (Si)** | 0.50 - 0.9 | | **Magnesium (Mg)** | 0.40 - 0.8 | | **Manganese (Mn)** | 0.20 - 0.6 | | **Copper (Cu)** | ≤ 0.20 | | **Iron (Fe)** | ≤ 0.35 | | **Chromium (Cr)** | ≤ 0.20 | | **Zinc (Zn)** | ≤ 0.20 | | **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 the strengthening Mg₂Si phase. The presence of Manganese (Mn) contributes to strength and grain structure control, which is beneficial for formability. The low copper content ensures good corrosion resistance. --- ### **3. Physical Properties** The typical physical properties of 6006 aluminum alloy are listed in the table below. | Property | Metric Value | Imperial Value | | :--- | :--- | :--- | | **Density** | 2.70 g/cm³ | 0.0975 lb/in³ | | **Melting Range** | ~ 615 - 655 °C | ~ 1140 - 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 GPa | 10,000 ksi | --- ### **4. Mechanical Properties** Mechanical properties vary with temper. The following are typical values for sheet or extruded products. **Temper: O (Annealed)** * **Tensile Strength:** 130 - 170 MPa (19 - 25 ksi) * **Yield Strength (0.2% Offset):** ≤ 70 MPa (≤ 10 ksi) * **Elongation (% in 50mm):** 20% min **Temper: T4 (Solution heat-treated and naturally aged)** * **Tensile Strength:** 190 - 230 MPa (28 - 33 ksi) * **Yield Strength (0.2% Offset):** 100 - 140 MPa (15 - 20 ksi) * **Elongation (% in 50mm):** 18% min **Temper: T6 (Solution heat-treated and artificially aged)** * **Tensile Strength:** 240 - 280 MPa (35 - 41 ksi) * **Yield Strength (0.2% Offset):** 210 - 250 MPa (30 - 36 ksi) * **Elongation (% in 50mm):** 10% min --- ### **5. Product Applications** 6006 alloy is used in various forms, including sheet, plate, and extrusions. Its primary applications leverage its excellent formability. * **Automotive Industry:** * Body panels (inner and outer) * Trim and molding components * Seat frames and parts requiring complex bends * **Appliances:** * Cabinets and decorative trim for refrigerators, washing machines, etc. * **General Engineering & Fabrication:** * Parts that require significant forming or roll-forming after heat treatment. * Welded structures where formability is a key concern. * **Building & Construction:** * Gutters, downspouts, and other formed architectural elements. --- ### **6. Key Characteristics & Advantages** * **Excellent Formability:** The standout feature of 6006 is its superior bendability and ductility, especially in the T4 temper, allowing for the creation of complex shapes without cracking. * **Good Strength after Heat Treatment:** While not as strong as 6061-T6, it develops substantial strength in the T6 temper, sufficient for many automotive and structural applications. * **High Surface Quality:** It provides an excellent surface for painting, anodizing, and other finishing processes, which is critical for visible automotive and appliance parts. * **Good Corrosion Resistance:** Possesses good resistance to atmospheric corrosion, consistent with other low-copper Al-Mg-Si alloys. * **Good Weldability:** Can be readily welded using common techniques like MIG and TIG. * **Brazeability:** Suitable for brazing operations, expanding its use in heat exchanger applications (though it is less common than 3003 for this purpose). In summary, **AA 6006 Aluminum Alloy** is a **high-formability variant** of the Al-Mg-Si family. It is engineered for applications where the manufacturing process involves significant shaping and forming, yet the final product requires a good combination of strength, corrosion resistance, and a high-quality aesthetic finish.
