Mechanical Properties (Typical by Temper)** The mechanical properties of 6064 are highly dependent on the temper. * **T4 Temper (Solution Heat-Treated and Naturally Aged):** * **Tensile Strength:** ~ 205 - 240 MPa * **Yield Strength (0.2% Offset):** ~ 110 - 140 MPa * **Elongation:** ~ 16 - 22% * **T6 Temper (Solution Heat-Treated and Artificially Aged):** * **Tensile Strength:** ~ 260 - 300 MPa * **Yield Strength (0.2% Offset):** ~ 240 - 280 MPa * **Elongation:** ~ 8 - 12% --- #### **4. International Standards** 6064 aluminum alloy is recognized in several major international standards, though it is less ubiquitous than 6061 or 6063. * **ASTM (USA):** * May be covered under general specifications like **ASTM B221** for extruded products, though it is not a primary listed alloy. * **ISO (International Organization for Standardization):** * **ISO 6361-2** (Wrought aluminum sheets/strips/plates) * **ISO 6362-2** (Wrought aluminum extruded products) * **GB (Chinese Standard):** **GB/T 3190** (Wrought Aluminum and Aluminum Alloy Chemical Composition). * **EN (European Standards):** May be listed under **EN 573-3** (Chemical composition). --- #### **5. Product Applications** Due to its specific property profile, 6064 is often selected for specialized applications. * **Specialized Structural Components:** Parts requiring a specific balance of strength and corrosion resistance. * **Marine Hardware:** Fittings and components exposed to marine environments. * **Transportation Industry:** Certain automotive or rail components where its properties are advantageous. * **General Engineering:** Machinery parts and structural applications. --- #### **6. Key Characteristics & Advantages** * **Good Strength:** Offers respectable mechanical properties, particularly in the T6 temper. * **Good Corrosion Resistance:** Inherits the good general corrosion resistance characteristic of Al-Mg-Si alloys. * **Heat-Treatable:** Can be strengthened through solution heat treatment and aging processes. * **Weldability:** Can be welded using common techniques, though properties in the heat-affected zone will be affected. * **Machinability:** Fair to good machinability in the T6 temper. --- **Disclaimer:** The information provided is typical and for reference purposes. Aluminum 6064 is a less commonly encountered alloy compared to 6061 or 6063, and its specifications can vary. For critical applications, it is essential to consult the specific material standards and the manufacturer's certified datasheet for precise chemical composition limits, guaranteed mechanical properties, and processing recommendations. In many cases, 6061 or 6063 may be specified as more readily available alternatives.
