# ISO-WD32250-T5 Magnesium

ISO-WD32250-T5 is ISO-WD32250 magnesium in the T5 temper. To achieve this temper, the metal is artificially aged until it meets standard mechanical property requirements. The graph bars on the material properties cards below compare ISO-WD32250-T5 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.
