6463-T4 Aluminum alloy,Aluminum 6463-T1 alloy，E FORU

### **Aluminum 6463-T1/T4 Alloy (EN AW-6463) - Product Introduction** **Aluminum 6463-T1/T4** represents the naturally aged tempers of the 6463 aluminum-magnesium-silicon alloy. The T1 temper is achieved by cooling from an elevated temperature shaping process (such as extrusion) and naturally aging, while the T4 temper involves solution heat treatment followed by natural aging. Both tempers offer a good combination of formability and moderate strength, serving as an intermediate condition suitable for further fabrication operations. --- #### **1.
