1100-H19 Aluminum alloy,Aluminum 1100-H19 alloy,E FORU

### **1100-H19 Aluminum Alloy Product Introduction** **1. Overview** 1100-H19 is an extra-hard strain-hardened temper of the commercially pure 1100 aluminum alloy, representing the hardest condition available in the H1X temper series. The "H19" temper designation indicates that the material has been strain-hardened beyond the standard full-hard condition (H18) to achieve even higher strength properties. This temper offers the ultimate in mechanical strength for the 1100 alloy series while maintaining the essential characteristics of pure aluminum, making it suitable for specialized applications requiring extreme rigidity and dimensional stability. **2. Chemical Composition (Typical, % by Weight)** The composition adheres to 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 contributes to achieving the maximum possible strength through extreme strain hardening.* **3.

This specialized temper offers mechanical properties that exceed the standard full-hard condition, making it ideal for applications where maximum rigidity, dimensional stability, and resistance to deformation are critical. While its formability is extremely limited, the H19 condition delivers unparalleled strength characteristics while maintaining the inherent benefits of the 1100 base alloy, including good corrosion resistance and surface quality. The combination of these properties makes 1100-H19 particularly valuable for precision electronic components, specialty packaging, high-stability electrical applications, and other demanding fields where conventional aluminum tempers cannot meet the rigorous strength requirements. This temper serves specialized applications that demand the absolute maximum performance from commercially pure aluminum.
