ZE41A (ZE41A-T5, 3.5101, M16410) Magnesium
ZE41A magnesium is a magnesium alloy. Cited properties are appropriate for the T5 temper. To achieve this temper, the metal is artificially aged until it meets standard mechanical property requirements. ZE41A is the ASTM designation for this material. M16410 is the UNS number.
It has a moderately high density among magnesium alloys. In addition, it has a fairly high base cost and a fairly high embodied energy.
The graph bars on the material properties cards below compare ZE41A magnesium 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.
