Chromium 33 vs. 70Ag-30Ni Alloy

Both chromium 33 and 70Ag-30Ni alloy are otherwise unclassified metals. They have a modest 30% of their average alloy composition in common, which, by itself, doesn't mean much. There are 13 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is chromium 33 and the bottom bar is 70Ag-30Ni alloy.
