AZ31B 0
VerifiedmetalAZ31B is a wrought magnesium alloy containing aluminum and zinc, commonly used in aerospace structural components, automotive parts, and portable equipment where light weight is critical. The O (annealed) temper provides optimal ductility and formability with reduced strength compared to work-hardened conditions, making it suitable for applications requiring complex forming operations and moderate loads at temperatures up to approximately 150°C.

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.
