4.Established usage in aviation and automotive structural applications.
Material shortcomings
1.Moderate weldability; welded joints typically show reduced strength and require careful process control.
2.Lower corrosion resistance compared to 5052 and 6061, needing surface protection for outdoor service.
3.Less formable than 5052, mostly manufactured via machining rather than cold forming.
4.Less globally standardized naming than 6061/7075, requiring clear material certification for international customers.
