1100-O Aluminum alloy,Aluminum 1100-O alloy,E FORU

### **1100-O Aluminum Alloy Product Introduction** **1. Overview** 1100-O is the annealed temper of the commercially pure 1100 aluminum alloy, representing the softest and most ductile condition in the aluminum temper series. The "O" temper designation indicates that the material has been fully annealed to achieve maximum softness and workability. This temper offers the lowest strength but highest formability among all tempers of 1100 aluminum, making it ideal for applications requiring severe forming, deep drawing, and spinning operations where maximum ductility is essential. **2. Chemical Composition (Typical, % by Weight)** The composition maintains the standard 1100 aluminum specification with controlled impurities. | Element | Content (%) | |---------|-------------| | **Aluminum (Al)** | ≥99.00 | | **Iron (Fe)** | ≤0.45 | | **Silicon (Si)** | ≤0.30 | | **Copper (Cu)** | 0.05-0.20 | | **Manganese (Mn)** | ≤0.05 | | **Zinc (Zn)** | ≤0.07 | | **Other Elements (Each)** | ≤0.03 | | **Other Elements (Total)** | ≤0.10 | *Note: The copper content (0.05-0.20%) provides slight strengthening while maintaining excellent workability in the annealed condition.* **3.

Mechanical Properties (Typical for O Temper)** The O temper provides the softest condition with maximum ductility for 1100 aluminum. | Property | Value | |----------|-------| | **Tensile Strength** | 75-105 MPa | | **Yield Strength (0.2% Offset)** | 25-40 MPa | | **Elongation (% in 50mm)** | 35-45% | | **Hardness (Brinell)** | 23-28 HB | *Key Characteristics of O Temper:* * **Maximum Ductility**: Highest elongation capability among all tempers * **Excellent Formability**: Ideal for deep drawing, spinning, and severe forming operations * **Low Strength**: Lowest mechanical strength but best workability * **Superior Workability**: Excellent for all types of forming and machining operations **5. Product Applications** 1100-O is supplied as sheet, strip, and plate for applications requiring maximum formability. * **Deep Drawing Components**: Kitchen utensils, pots, pans, and containers * **Spun Products**: Reflectors, covers, and decorative items * **Chemical Equipment**: Tanks, vessels, and linings for chemical processing * **Electrical Industry**: Transformer windings, capacitor shells, and flexible conductors * **Architectural Applications**: Complex formed decorative elements and trim * **Food Processing Equipment**: Containers and processing vessels * **General Metal Working**: Prototypes and complex-shaped components **6. International Standards** 1100-O is recognized globally under various standardization systems. | Standard System | Designation | |-----------------|-------------| | **ISO** | Al99.0Cu O | | **EN (Europe)** | EN AW-1100A O | | **ASTM (USA)** | ASTM B209 1100 O | | **UNS (USA)** | UNS A91100 O | | **JIS (Japan)** | A1100 O | | **GB (China)** | 1100 O | --- **Summary** **1100-O Aluminum Alloy** represents the **fully annealed, softest temper** in the 1100 aluminum series, providing the **maximum ductility and formability** while maintaining the fundamental benefits of commercially pure aluminum. This temper offers superior workability characteristics including exceptional deep drawing capability, excellent elongation, and easy formability, making it the preferred choice for applications requiring severe deformation and complex shaping. The combination of high workability with good corrosion resistance and reasonable conductivity makes 1100-O an indispensable material for deep drawing applications, spun products, and any manufacturing process where maximum formability is essential. Its excellent all-around workability and proven performance make it one of the most versatile aluminum tempers for general manufacturing and specialized forming applications.
