70Ag-30Ni Alloy vs. AWS E385

70Ag-30Ni alloy belongs to the otherwise unclassified metals classification, while AWS E385 belongs to the iron alloys. They have a modest 25% 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 70Ag-30Ni alloy and the bottom bar is AWS E385.
