R30001 Cobalt vs. EN 1.4889 Cast Nickel

R30001 cobalt belongs to the cobalt alloys classification, while EN 1.4889 cast nickel belongs to the nickel alloys. They have a modest 34% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is R30001 cobalt and the bottom bar is EN 1.4889 cast nickel.
