EN 2.4654 Nickel vs. ZK61A Magnesium

EN 2.4654 nickel belongs to the nickel alloys classification, while ZK61A magnesium belongs to the magnesium alloys. There are 28 material properties with values for both materials. Properties with values for just one material (3, 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 EN 2.4654 nickel and the bottom bar is ZK61A magnesium.
