Grade 365 Molybdenum vs. Grade N7M Nickel

Grade 365 molybdenum belongs to the otherwise unclassified metals classification, while grade N7M nickel belongs to the nickel alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (5, in this case) are not shown.

For each property being compared, the top bar is grade 365 molybdenum and the bottom bar is grade N7M nickel.
