Nickel Beryllium 360 vs. ZK51A Magnesium

Nickel beryllium 360 belongs to the nickel alloys classification, while ZK51A magnesium belongs to the magnesium alloys. There are 24 material properties with values for both materials. Properties with values for just one material (7, 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 nickel beryllium 360 and the bottom bar is ZK51A magnesium.
