### **1350-H16 Aluminum Alloy Product Introduction** **1. Overview** 1350-H16 is a strain-hardened temper of the electrical conductor grade 1350 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 mechanical strength while maintaining good electrical conductivity, making it suitable for electrical applications requiring greater rigidity and tensile strength. **2.

International Standards** 1350-H16 is recognized under major international standardization systems. | Standard System | Designation | |-----------------|-------------| | **EN (Europe)** | EN AW-1350A H16 | | **IEC** | IEC 60104 | | **ASTM (USA)** | ASTM B230/B231 1350 H16 | | **UNS (USA)** | UNS A91350 H16 | | **JIS (Japan)** | A1350 H16 | | **GB (China)** | 1350 H16 | --- **Summary** **1350-H16 Aluminum Alloy** represents a **three-quarter hard temper** that provides **enhanced mechanical strength** while maintaining **good electrical conductivity**. This temper offers significantly higher tensile and yield strength compared to the H14 condition, making it ideal for electrical applications where mechanical integrity and resistance to deformation are critical. While its formability is limited to simple bending operations, the H16 temper maintains adequate electrical conductivity for most power transmission applications. The combination of these properties makes 1350-H16 particularly valuable for heavy-duty busbars, transmission lines, and electrical components operating in demanding environments where both mechanical strength and electrical performance are essential requirements.
