2007-T3 Aluminum alloy,Aluminum 2007-T3 alloy,E FORU

### **2007-T3 Aluminum Alloy Product Introduction** **1. Overview** 2007-T3 is a specific temper of the free-machining aluminum-copper alloy 2007, representing a solution heat-treated, cold worked, and naturally aged condition. The "T3" temper designation indicates that the material has been solution heat-treated, followed by cold working to achieve higher strength, and then naturally aged to a substantially stable condition. This temper offers an excellent combination of high strength, good machinability, and improved stress corrosion resistance. **2.
