Grade N12MV Nickel vs. R30003 Cobalt
Grade N12MV nickel belongs to the nickel alloys classification, while R30003 cobalt belongs to the cobalt alloys. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 23 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.
For each property being compared, the top bar is grade N12MV nickel and the bottom bar is R30003 cobalt.
