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.
