ZK40A Magnesium vs. N06002 Nickel

ZK40A magnesium belongs to the magnesium alloys classification, while N06002 nickel belongs to the nickel alloys. 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 ZK40A magnesium and the bottom bar is N06002 nickel.
