2014-O Aluminum alloy,Aluminum 2014-O alloy,E FORU

### **2014-O Aluminum Alloy Product Introduction** **1. Overview** 2014-O is the annealed temper of the high-strength aluminum-copper alloy 2014 from the 2xxx series. The "O" temper designation indicates that the material has been fully annealed to achieve maximum softness and workability. This condition offers the lowest strength but highest formability among all tempers of 2014 aluminum, making it ideal for applications requiring severe forming, deep drawing, and complex shaping operations before subsequent heat treatment. **2.

Product Applications** 2014-O is primarily used for components requiring extensive forming before heat treatment. * **Aerospace Components**: Complex-shaped aircraft parts before heat treatment * **Automotive Parts**: Deep-drawn components for high-performance vehicles * **Military Equipment**: Complex-shaped defense components * **Structural Components**: Formed structural elements for subsequent hardening * **Industrial Machinery**: Complex-shaped machine parts * **Sporting Goods**: Formed components for high-performance equipment * **Prototype Development**: Components requiring extensive forming operations **6. International Standards** 2014-O is recognized under major international standardization systems. | Standard System | Designation | |-----------------|-------------| | **ISO** | AlCu4SiMg O | | **EN (Europe)** | EN AW-2014A O | | **ASTM (USA)** | ASTM B209 2014 O | | **UNS (USA)** | UNS A92014 O | | **JIS (Japan)** | A2014 O | | **GB (China)** | 2A14 O | --- **Summary** **2014-O Aluminum Alloy** represents the **fully annealed, softest temper** in the 2014 aluminum series, providing **maximum formability and workability** for manufacturing processes requiring severe deformation. This temper condition is particularly valuable as an intermediate manufacturing stage, allowing manufacturers to perform demanding forming operations such as deep drawing, spinning, and complex bending before applying heat treatment to develop the alloy's characteristic high strength. The combination of excellent formability in the O temper with the potential for subsequent strengthening through heat treatment makes 2014-O an essential material for aerospace components, automotive parts, and other applications where complex shapes must be formed before achieving final mechanical properties. This processing flexibility establishes 2014-O as a crucial manufacturing material across various high-performance industries.
