1100-H16 Aluminum alloy,Aluminum 1100-H16 alloy,E FORU

### **1100-H16 Aluminum Alloy Product Introduction** **1. Overview** 1100-H16 is a strain-hardened temper of the commercially pure 1100 aluminum alloy, representing a three-quarter hard condition. The "H16" temper designation indicates that the material has been strain-hardened to achieve a strength level approximately three-quarters of the way between the O (annealed) temper and H18 (full-hard) temper. This temper offers higher strength while maintaining limited formability, making it suitable for applications requiring greater rigidity and dimensional stability than softer tempers can provide. **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%) contributes to the enhanced strength characteristics in the strain-hardened condition.* **3. Physical Properties** | Property | Value | |----------|-------| | **Density** | 2.71 g/cm³ | | **Melting Point** | 643-657°C | | **Electrical Conductivity** | 59% IACS | | **Thermal Conductivity** | 218 W/(m·K) | | **Coefficient of Thermal Expansion** | 23.6 × 10⁻⁶/K (20-100°C) | | **Modulus of Elasticity** | 69 GPa | **4. Mechanical Properties (Typical for H16 Temper)** The H16 temper provides three-quarter hard mechanical properties with enhanced strength. | Property | Value | |----------|-------| | **Tensile Strength** | 140-165 MPa | | **Yield Strength (0.2% Offset)** | 130-150 MPa | | **Elongation (% in 50mm)** | 6-12% | | **Hardness (Brinell)** | 38-45 HB | *Key Characteristics of H16 Temper:* * **Enhanced Strength**: Higher mechanical strength compared to H14 temper * **Good Rigidity**: Excellent dimensional stability and resistance to deformation * **Limited Formability**: Suitable for simple bending operations only * **Maintained Conductivity**: Preserves reasonable electrical and thermal conductivity **5. Product Applications** 1100-H16 is primarily supplied as sheet and strip for applications requiring higher strength and rigidity. * **Architectural Applications**: Structural panels, roofing sheets requiring high stiffness * **Electronic Enclosures**: Housing and chassis requiring dimensional stability * **Industrial Components**: Machine parts, brackets, and support elements * **Signage Industry**: Rigid sign boards and identification plates * **Electrical Industry**: Sturdy busbars and conductive components * **Transportation**: Interior panels and structural components * **Consumer Durables**: Appliance components and hardware parts **6. International Standards** 1100-H16 is recognized globally under various standardization systems. | Standard System | Designation | |-----------------|-------------| | **ISO** | Al99.0Cu H16 | | **EN (Europe)** | EN AW-1100A H16 | | **ASTM (USA)** | ASTM B209 1100 H16 | | **UNS (USA)** | UNS A91100 H16 | | **JIS (Japan)** | A1100 H16 | | **GB (China)** | 1100 H16 | --- **Summary** **1100-H16 Aluminum Alloy** represents a **three-quarter hard temper** that provides **enhanced strength and rigidity** while maintaining the fundamental benefits of commercially pure aluminum. This temper offers significantly higher mechanical properties compared to the H14 condition, making it ideal for applications where dimensional stability and resistance to deformation are critical. While its formability is limited to simple bending operations, the H16 temper maintains good corrosion resistance and reasonable conductivity inherent to the 1100 alloy series. The combination of these properties makes 1100-H16 particularly valuable for architectural applications, electronic enclosures, industrial components, and other applications where both structural integrity and the classic advantages of pure aluminum are required.
