R30003 Cobalt vs. N10001 Nickel
R30003 cobalt belongs to the cobalt alloys classification, while N10001 nickel belongs to the nickel alloys. They have a modest 30% 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 (8, in this case) are not shown.
For each property being compared, the top bar is R30003 cobalt and the bottom bar is N10001 nickel.
