AWS BVAu-7 vs. AWS ENiCrMo-10

AWS BVAu-7 belongs to the otherwise unclassified metals classification, while AWS ENiCrMo-10 belongs to the nickel alloys. They have a modest 25% 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 (10, in this case) are not shown.

For each property being compared, the top bar is AWS BVAu-7 and the bottom bar is AWS ENiCrMo-10.
