1100-H12 Aluminum alloy,Aluminum 1100-H12 alloy,E FORU

### **1100-H12 Aluminum Alloy Product Introduction** **1. Overview** 1100-H12 is a strain-hardened temper of the commercially pure 1100 aluminum alloy, representing a quarter-hard condition. The "H12" temper designation indicates that the material has been strain-hardened to achieve a strength level approximately one-quarter of the way between the O (annealed) temper and H18 (full-hard) temper. This temper offers an optimal balance between strength and formability, making it particularly suitable for applications requiring moderate strength with good workability and excellent corrosion resistance. **2. Chemical Composition (Typical, % by Weight)** The composition follows 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 controlled copper content (0.05-0.20%) provides enhanced strength while maintaining good workability and corrosion resistance.* **3.
