5083 Aluminum H323

Verifiedmetal

5083-H323 is a non-heat-treatable aluminum-magnesium alloy (3–4.5% Mg) with moderate strength and excellent seawater corrosion resistance, commonly used in marine structures, pressure vessels, and welded aerospace applications. The H323 temper (strain-hardened and partially annealed) provides improved formability and stress-relief characteristics compared to full-hard conditions while maintaining good strength, making it suitable for applications requiring both workability and moderate mechanical properties.
