5083 Aluminum H321
VerifiedmetalUNS A95083
5083 Aluminum H321 is a non-heat-treatable aluminum-magnesium alloy (nominally 4.4% Mg) in a strain-hardened and stress-relieved condition, offering excellent seawater corrosion resistance and weldability with moderate strength suitable for marine structures, pressure vessels, and welded aerospace applications. The H321 temper provides controlled mechanical properties and dimensional stability through controlled work-hardening followed by thermal stress relief, maintaining corrosion resistance while reducing residual stresses from fabrication.

Industry-Specific
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
