EN 2.4964 Cobalt vs. N08024 Nickel

EN 2.4964 cobalt belongs to the cobalt alloys classification, while N08024 nickel belongs to the nickel alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is EN 2.4964 cobalt and the bottom bar is N08024 nickel.
