5456 aluminum is a non-heat-treatable Al-Mg alloy (nominally 5% Mg) with excellent seawater corrosion resistance, widely used in marine structures and welded pressure vessels. The H321 temper (strain-hardened and stress-relieved) provides moderate strength with improved stress-corrosion cracking resistance compared to fully work-hardened conditions, making it suitable for service in aggressive marine environments.
