5456-O is an aluminum-magnesium alloy (nominally 5% Mg) in the fully annealed condition, providing excellent corrosion resistance in marine and seawater environments with moderate strength suitable for welded structures and pressure vessels. The O temper offers maximum ductility and elongation at break, making it ideal for applications requiring formability and weldability over strength, with availability in extruded and rolled forms per aerospace specifications AMS-QQ-A-200/7 and AMS-QQ-A-250/9.
