### **Aluminum 8017-H12 Alloy Technical Datasheet** --- #### **1. Product Overview** **Aluminum 8017-H12** is a specialized wrought aluminum alloy from the 8000 series, supplied in quarter-hard temper. This non-heat-treatable alloy is designed for applications requiring a balance of moderate strength and good formability. The H12 temper indicates the material has been strain-hardened to achieve approximately quarter-hard strength level, making it suitable for forming operations that require more strength than fully annealed material but greater formability than half-hard tempers. --- #### **2.
