EN 2.4654 Nickel vs. G-CoCr28 Cobalt

EN 2.4654 nickel belongs to the nickel alloys classification, while G-CoCr28 cobalt belongs to the cobalt alloys. They have a modest 37% 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 (1, in this case) are not shown.

For each property being compared, the top bar is EN 2.4654 nickel and the bottom bar is G-CoCr28 cobalt.
