EV31A Magnesium vs. C43000 Brass

EV31A magnesium belongs to the magnesium alloys classification, while C43000 brass belongs to the copper alloys. There are 23 material properties with values for both materials. Properties with values for just one material (12, 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 EV31A magnesium and the bottom bar is C43000 brass.
