### **Product Datasheet: 2080 Aluminum Alloy** --- #### **1. Overview** 2080 Aluminum Alloy is a premium aluminum-lithium (Al-Li) alloy developed for specialized aerospace applications requiring an optimal balance of medium strength, excellent damage tolerance, and superior corrosion resistance. As part of the advanced Al-Li alloy family, it offers significant weight savings while maintaining good formability and weldability. The alloy is particularly suitable for applications where damage tolerance and corrosion resistance are more critical than ultimate strength, making it ideal for certain aircraft structural components and specialized defense applications. --- #### **2.
