AZ31B Magnesium
VerifiedmetalAZ31B is a wrought magnesium alloy containing aluminum and zinc, widely used in aerospace, automotive, and defense applications where lightweight structures are required. The alloy offers moderate strength (yield ~160-275 MPa depending on temper), good corrosion resistance, and low density (~1.8 g/cm³), with F (as-fabricated), O (annealed), and H24 (strain-hardened) tempers providing increasingly higher strength at the expense of ductility.

Export Control
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.
