ZE41A Magnesium vs. Grade 360 Molybdenum

ZE41A magnesium belongs to the magnesium alloys classification, while grade 360 molybdenum belongs to the otherwise unclassified metals. There are 20 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is ZE41A magnesium and the bottom bar is grade 360 molybdenum.
