ISO-WD32350-H24 Magnesium
ISO-WD32350-H24 is ISO-WD32350 magnesium in the H24 temper. To achieve this temper, the metal is strain hardened, and then partially annealed, to a strength that is roughly halfway between annealed (O) and full-hard (H28).
It has the highest strength and lowest ductility compared to the other variants of ISO-WD32350 magnesium.
The graph bars on the material properties cards below compare ISO-WD32350-H24 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.
