EN 1.4889 Cast Nickel vs. R30006 Cobalt

EN 1.4889 cast nickel belongs to the nickel alloys classification, while R30006 cobalt belongs to the cobalt alloys. They have a modest 34% 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 (9, in this case) are not shown.

For each property being compared, the top bar is EN 1.4889 cast nickel and the bottom bar is R30006 cobalt.
