EN 2.4878 Nickel vs. 70Ag-30Ni Alloy

EN 2.4878 nickel belongs to the nickel alloys classification, while 70Ag-30Ni alloy belongs to the otherwise unclassified metals. 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 (15, in this case) are not shown.

For each property being compared, the top bar is EN 2.4878 nickel and the bottom bar is 70Ag-30Ni alloy.
