5182-O Aluminum alloy,Aluminum 5182-O alloy,E FORU

### **5182-O Aluminum Alloy Technical Datasheet** **Material Overview** 5182-O is the annealed temper of the aluminum-magnesium alloy 5182, characterized by its maximum ductility and formability. In the "O" (annealed) condition, the material has been heated to relieve internal stresses and achieve the softest state, making it ideal for severe forming operations. This alloy maintains the excellent corrosion resistance typical of the 5xxx series while offering exceptional workability for complex fabrication processes. --- ### **1.
