5456 Aluminum O
Verifiedmetal5456-O is an aluminum-magnesium alloy (nominally 5% Mg) in the fully annealed condition, providing excellent corrosion resistance in marine and seawater environments with moderate strength suitable for welded structures and pressure vessels. The O temper offers maximum ductility and elongation at break, making it ideal for applications requiring formability and weldability over strength, with availability in extruded and rolled forms per aerospace specifications AMS-QQ-A-200/7 and AMS-QQ-A-250/9.

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.
