Nickel 617 vs. ZK60A Magnesium

Nickel 617 belongs to the nickel alloys classification, while ZK60A magnesium belongs to the magnesium 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 nickel 617 and the bottom bar is ZK60A magnesium.
