Balanced strength, very good formability and long-lasting corrosion resistance for general sheet work, welded structures and marine environments.
5XXX Series
Aluminium 5251 is a medium-strength, magnesium- and manganese-alloyed, non-heat-treatable 5XXX series sheet alloy. It combines very good cold forming and welding properties with high corrosion resistance in marine, industrial and atmospheric environments. It is a versatile choice for boat parts, panels, pressed components and welded fabrications.
