70Ag-30Ni Alloy vs. AWS BNi-2

70Ag-30Ni alloy belongs to the otherwise unclassified metals classification, while AWS BNi-2 belongs to the nickel alloys. They have a modest 30% 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 (7, in this case) are not shown.

For each property being compared, the top bar is 70Ag-30Ni alloy and the bottom bar is AWS BNi-2.
