AWS E410NiMo vs. EZ33A Magnesium

AWS E410NiMo belongs to the iron alloys classification, while EZ33A magnesium belongs to the magnesium alloys. There are 24 material properties with values for both materials. Properties with values for just one material (10, 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 E410NiMo and the bottom bar is EZ33A magnesium.
