(Summary description)EN-MC21120-F Magnesium EN-MC21120-F is EN-MC21120 magnesium in the as-fabricated (no temper or treatment) condition. It has the lowest strength compared to the other variants of EN-MC21120 magnesium. The graph bars on the material properties cards below compare EN-MC21120-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.
