AWS BAg-2a vs. AWS ENiCu-7

AWS BAg-2a belongs to the otherwise unclassified metals classification, while AWS ENiCu-7 belongs to the nickel alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 17 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is AWS BAg-2a and the bottom bar is AWS ENiCu-7.
