AM50A Magnesium vs. Grade M35-2 Nickel

AM50A magnesium belongs to the magnesium alloys classification, while grade M35-2 nickel belongs to the nickel 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 AM50A magnesium and the bottom bar is grade M35-2 nickel.
