5456 Aluminum H321
Verifiedmetal5456 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.

Quality & Standards
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.
