Mechanical Properties (Typical for T6 Temper)** The T6 temper (Solution Heat-Treated and Artificially Aged) defines the key high-strength characteristics of this product. These are typical minimum values for sheet or extruded products. | Property | Metric Value | Imperial Value | | :--- | :--- | :--- | | **Tensile Strength** | ~ 240 - 290 MPa | ~ 35 - 42 ksi | | **Yield Strength (0.2% Offset)** | ~ 215 - 240 MPa | ~ 31 - 35 ksi | | **Elongation (in 50mm)** | ~ 8 - 12 % | ~ 8 - 12 % | | **Hardness (Brinell)** | ~ 75 - 85 HB | ~ 75 - 85 HB | **Note:** The T6 temper represents the peak-aged condition, offering the best strength and hardness at the expense of some ductility compared to the T4 temper. --- #### **4. International Standards** 6053 Aluminum Alloy is specified in several key international standards: * **ASTM (USA):** While less common than other 6xxx alloys, it may be covered under specifications like **ASTM B211** for bar, rod, and wire, or **ASTM B221** for extruded profiles. * **AA (Aluminum Association, USA):** The Aluminum Association maintains the definitive registration for alloy 6053 and its tempers, including T6. * **UNS (Unified Numbering System):** **UNS A96053** * **SAE (Society of Automotive Engineers):** **SAE J454** covers the chemical composition. --- #### **5. Product Applications** 6053-T6 is selected for applications that require high strength, good fatigue resistance, and dimensional stability. * **High-Strength Structural Components:** Used in automotive and transportation structures where a high strength-to-weight ratio is critical. * **Aerospace Applications:** Non-critical aircraft components, fittings, and structures that benefit from its combination of strength and corrosion resistance. * **Marine Hardware:** Components such as fittings, rails, and frames that require resistance to saltwater corrosion and good mechanical strength. * **Precision Machined Parts:** The T6 condition provides excellent machinability, allowing for the production of stable, high-tolerance components. * **Sporting Goods:** Used in high-performance bicycle frames, components, and other sporting equipment where lightweight and rigidity are required. --- #### **6. Key Characteristics & Advantages** * **High Strength:** The T6 temper provides the highest practical strength for this alloy, making it suitable for structural applications. * **Good Ductility:** Despite its high strength, it retains sufficient elongation for reliable service and to withstand minor impacts. * **Excellent Corrosion Resistance:** Maintains the good general and atmospheric corrosion resistance characteristic of Al-Mg-Si alloys. * **Dimensional Stability:** The artificially aged T6 condition is a stable temper, meaning mechanical properties and dimensions are less likely to change over time compared to a T4 state. * **Good Machinability:** In the T6 temper, the alloy machines well, producing good surface finishes. **Disclaimer:** The information provided is typical and for reference purposes.
