Grade CW6M Nickel vs. ISO-WD32350 Magnesium

Grade CW6M nickel belongs to the nickel alloys classification, while ISO-WD32350 magnesium belongs to the magnesium alloys. There are 25 material properties with values for both materials. Properties with values for just one material (5, 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 grade CW6M nickel and the bottom bar is ISO-WD32350 magnesium.
