ISO-WD32260-T5 Magnesium
ISO-WD32260-T5 is ISO-WD32260 magnesium in the T5 temper. To achieve this temper, the metal is artificially aged until it meets standard mechanical property requirements. It has the highest strength and highest ductility compared to the other variants of ISO-WD32260 magnesium.
The graph bars on the material properties cards below compare ISO-WD32260-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.
