Alclad 2219-T62 Aluminum alloy,Aluminum 2219-T62 alloy,E FORU

### **Product Datasheet: Alclad 2219-T62 Aluminum Alloy** --- #### **1. Overview** Alclad 2219-T62 Aluminum Alloy is a high-strength aluminum-copper alloy supplied in the T62 temper (solution heat-treated, cold worked, and artificially aged) with a protective aluminum cladding layer. This temper provides a superior combination of high strength, good stress corrosion resistance, and excellent weldability, making it ideal for aerospace applications requiring robust mechanical performance and environmental durability. The artificial aging process optimizes the strength-toughness balance while maintaining the sacrificial corrosion protection of the Alclad coating. --- #### **2.
