AWS BAg-8 vs. EN-MC65210 Magnesium

AWS BAg-8 belongs to the otherwise unclassified metals classification, while EN-MC65210 magnesium belongs to the magnesium alloys. There are 15 material properties with values for both materials. Properties with values for just one material (15, 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 AWS BAg-8 and the bottom bar is EN-MC65210 magnesium.
