AZ31B Magnesium F

Verifiedmetal

AZ31B is a wrought magnesium alloy containing aluminum and zinc providing moderate strength with good corrosion resistance, widely used in aerospace and automotive applications where weight reduction is critical. The F (as-fabricated) temper represents the material in its as-extruded or as-forged condition without heat treatment, offering consistent properties suitable for structural components requiring ductility and formability over peak strength.

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.
