ISO-WD43150 Magnesium vs. Grade 31 Titanium

ISO-WD43150 magnesium belongs to the magnesium alloys classification, while grade 31 titanium belongs to the titanium alloys. There are 29 material properties with values for both materials. Properties with values for just one material (2, 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 ISO-WD43150 magnesium and the bottom bar is grade 31 titanium.
