AWS BAu-5 vs. Grade CX2M Nickel

AWS BAu-5 belongs to the otherwise unclassified metals classification, while grade CX2M nickel belongs to the nickel alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 15 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 AWS BAu-5 and the bottom bar is grade CX2M nickel.
