### **1350-H111 Aluminum Alloy Product Introduction** **1. Overview** 1350-H111 is a strain-hardened temper of the electrical conductor grade 1350 aluminum alloy, representing an annealed condition with slight strain hardening. The "H111" temper designation indicates that the material has been strain-hardened to a lesser degree than H11 temper, followed by a partial annealing process to achieve specific mechanical properties. This temper offers an optimal balance between electrical conductivity and mechanical strength, making it particularly suitable for electrical applications requiring both good conductivity and adequate formability. **2.
