CC140C Copper vs. EN-MC65210 Magnesium

CC140C copper belongs to the copper alloys classification, while EN-MC65210 magnesium belongs to the magnesium alloys. There are 27 material properties with values for both materials. Properties with values for just one material (4, 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 CC140C copper and the bottom bar is EN-MC65210 magnesium.
