# AZ63A-F Magnesium

AZ63A-F magnesium is AZ63A magnesium in the as-fabricated (no temper or treatment) condition. It has the lowest strength compared to the other variants of AZ63A magnesium. The graph bars on the material properties cards below compare AZ63A-F magnesium 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.
