ISO-WD32260-T6 Magnesium
ISO-WD32260-T6 is ISO-WD32260 magnesium in the T6 temper. To achieve this temper, the metal is solution heat-treated and artificially aged until it meets standard mechanical property requirements. It has the lowest ductility compared to the other variants of ISO-WD32260 magnesium.
The graph bars on the material properties cards below compare ISO-WD32260-T6 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.
