Nickel 80A vs. AWS BCo-1

Nickel 80A belongs to the nickel alloys classification, while AWS BCo-1 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 18 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is nickel 80A and the bottom bar is AWS BCo-1.
