AZ31B
VerifiedmetalUNS M11311
AZ31B is a wrought magnesium alloy containing aluminum and zinc, widely used in aerospace, automotive, and defense applications where weight reduction is critical. It offers moderate strength with good corrosion resistance and machinability, with strength and ductility varying significantly by temper condition from annealed (O) to strain-hardened (H24, H26) states.

Regulatory Screening
Environmental
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.
