EN-MC95310 Magnesium vs. Z13004 Zinc

EN-MC95310 magnesium belongs to the magnesium alloys classification, while Z13004 zinc belongs to the zinc alloys. There are 28 material properties with values for both materials. Properties with values for just one material (3, 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 EN-MC95310 magnesium and the bottom bar is Z13004 zinc.
