EN-MC21220 Magnesium vs. Solder Alloy 712

EN-MC21220 magnesium belongs to the magnesium alloys classification, while solder alloy 712 belongs to the otherwise unclassified metals. There are 22 material properties with values for both materials. Properties with values for just one material (9, 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-MC21220 magnesium and the bottom bar is solder alloy 712.
