EN 1.4889 Cast Nickel vs. EN 2.4964 Cobalt

EN 1.4889 cast nickel belongs to the nickel alloys classification, while EN 2.4964 cobalt belongs to the cobalt alloys. They have a modest 33% 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 EN 1.4889 cast nickel and the bottom bar is EN 2.4964 cobalt.
