Grade CU5MCuC Nickel vs. AWS BAu-5

Grade CU5MCuC nickel belongs to the nickel alloys classification, while AWS BAu-5 belongs to the otherwise unclassified metals. 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 (12, in this case) are not shown.

For each property being compared, the top bar is grade CU5MCuC nickel and the bottom bar is AWS BAu-5.
