### **1350-H12 Aluminum Alloy Product Introduction** **1. Overview** 1350-H12 is a strain-hardened temper of the electrical conductor grade 1350 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 electrical conductivity, mechanical strength, and formability, making it particularly suitable for electrical applications requiring good conductivity with moderate strength. **2.
