Grade CW6M Nickel vs. R30001 Cobalt

Grade CW6M nickel belongs to the nickel alloys classification, while R30001 cobalt belongs to the cobalt alloys. They have a modest 23% 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 grade CW6M nickel and the bottom bar is R30001 cobalt.
