60Cr-40Ni Alloy vs. R30012 Cobalt
60Cr-40Ni alloy belongs to the otherwise unclassified metals classification, while R30012 cobalt belongs to the cobalt alloys. They have a modest 32% of their average alloy composition in common, which, by itself, doesn't mean much. There are 18 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 60Cr-40Ni alloy and the bottom bar is R30012 cobalt.
