6053-T4 Aluminum alloy,Aluminum 6053-T4 alloy,E FORU

### **6053-T4 Aluminum Alloy: Product Introduction** **Overview** 6053-T4 is a heat-treatable aluminum-magnesium-silicon (Al-Mg-Si) alloy supplied in the solution heat-treated and naturally aged temper. This T4 condition provides a superior combination of **good strength and excellent ductility** right after forming, making it an ideal choice for components that require significant forming operations after a solution heat treatment. It is known for its good corrosion resistance and is often used in brazed assemblies where post-brazing age-hardening develops its final strength. --- #### **1. Chemical Composition (Weight %)** The chemical composition is fundamental to the alloy's properties and conforms to international standards. | Element | Minimum (%) | Maximum (%) | | :--- | :--- | :--- | | Silicon (Si) | 0.40 | 0.7 | | Iron (Fe) | - | 0.15 | | Copper (Cu) | 0.10 | 0.20 | | Manganese (Mn) | - | 0.10 | | Magnesium (Mg) | 0.50 | 0.9 | | Chromium (Cr) | 0.15 | 0.35 | | Zinc (Zn) | - | 0.10 | | Titanium (Ti) | - | 0.10 | | Other (Each) | - | 0.05 | | Other (Total) | - | 0.15 | | **Aluminum (Al)** | **Balance** | | --- #### **2. Physical Properties** The physical properties of 6053-T4 are similar to other Al-Mg-Si alloys and are largely unaffected by temper. | Property | Metric Value | Imperial Value | | :--- | :--- | :--- | | **Density** | 2.70 g/cm³ | 0.0975 lb/in³ | | **Melting Range** | ~ 555 - 650 °C | ~ 1030 - 1200 °F | | **Electrical Conductivity** | ~ 50-55% IACS* | ~ 50-55% IACS* | | **Thermal Conductivity** | ~ 180 W/m·K | ~ 1048 BTU·in/(hr·ft²·°F) | | **Coefficient of Thermal Expansion (20-100°C)** | 23.4 x 10⁻⁶ /°C | 13.0 x 10⁻⁶ /°F | *IACS: International Annealed Copper Standard --- #### **3. Mechanical Properties (Typical for T4 Temper)** The T4 temper (Solution Heat-Treated and Naturally Aged) defines the key mechanical characteristics of this product. These values are typical for sheet or strip products. | Property | Metric Value | Imperial Value | | :--- | :--- | :--- | | **Tensile Strength** | ~ 205 - 240 MPa | ~ 30 - 35 ksi | | **Yield Strength (0.2% Offset)** | ~ 95 - 125 MPa | ~ 14 - 18 ksi | | **Elongation (in 50mm)** | ~ 18 - 25 % | ~ 18 - 25 % | | **Hardness (Brinell)** | ~ 55 - 65 HB | ~ 55 - 65 HB | **Note:** The T4 temper offers a excellent balance for forming. The alloy can be further artificially aged to a T6 or T64 temper to achieve higher strength, though this will result in reduced ductility. --- #### **4. International Standards** 6053 Aluminum Alloy is specified in several key international standards: * **ASTM (USA):** While less common than other alloys, it may be covered under specifications like ASTM B209 for sheet and plate. It is most reliably tracked under the Aluminum Association system. * **AA (Aluminum Association, USA):** The Aluminum Association maintains the definitive registration for alloy 6053 and its tempers, including T4. * **UNS (Unified Numbering System):** UNS A96053 * **EN (European Standards):** It may be comparable to alloys in the EN AW-6xxx series, though not a direct equivalent. --- #### **5. Product Applications** 6053-T4 is selected for applications that benefit from its combination of intermediate strength and high formability. * **Automotive Heat Exchangers:** Used for tubes and fins in radiators and charge air coolers, where it can be formed in the T4 state and then gain strength during the brazing cycle and subsequent aging. * **Complex Stamped or Formed Parts:** Components that require more strength than the O-temper can provide but still need significant ductility for the forming process. * **Brazed Assemblies:** Suitable for flux-brazed assemblies where the component is used in the T4 state and the brazing process serves as a partial solution heat treatment. * **Structural Components:** Parts that are formed and then used without a full artificial aging process, leveraging the stable T4 properties. --- #### **6. Key Characteristics & Advantages** * **Excellent Formability:** The T4 temper provides high ductility, allowing for complex bending, stamping, and drawing operations. * **Good Strength-to-Weight Ratio:** Offers a significant strength advantage over the O-temper while maintaining a low weight. * **Age-Hardenable:** The T4 condition is metastable, meaning it can be artificially aged (to a T6 temper) to achieve significantly higher strength levels if required for the final application. * **Good Corrosion Resistance:** Inherits the good general corrosion resistance characteristic of Al-Mg-Si alloys. * **Brazing Compatibility:** Well-suited for brazing processes, as the thermal cycle can contribute to its final temper and strength. **Disclaimer:** The information provided is typical and for reference purposes.
