EN-MC65210 Magnesium vs. Commercially Pure Zinc
EN-MC65210 magnesium belongs to the magnesium alloys classification, while commercially pure zinc belongs to the zinc alloys. There are 26 material properties with values for both materials. Properties with values for just one material (5, 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-MC65210 magnesium and the bottom bar is commercially pure zinc.
