# ISO-WD32250-F Magnesium

ISO-WD32250-F is ISO-WD32250 magnesium in the as-fabricated (no temper or treatment) condition. The graph bars on the material properties cards below compare ISO-WD32250-F to other magnesium alloys (top) and the entire database (bottom). A full bar means this is the highest value in the relevant set. A half-full bar means it's 50% of the highest, and so on.
