AWS BNi-6 vs. AWS BVAu-7

AWS BNi-6 belongs to the nickel alloys classification, while AWS BVAu-7 belongs to the otherwise unclassified metals. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 16 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is AWS BNi-6 and the bottom bar is AWS BVAu-7.
