EQ21A Magnesium vs. Grade 705C Zirconium

EQ21A magnesium belongs to the magnesium alloys classification, while grade 705C zirconium belongs to the otherwise unclassified metals. There are 20 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 EQ21A magnesium and the bottom bar is grade 705C zirconium.
