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.
