Annealed 70Ag-30Ni Alloy vs. Annealed ASTM B522 Class I
Both annealed 70Ag-30Ni alloy and annealed ASTM B522 class I are otherwise unclassified metals. Both are furnished in the annealed condition. 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 (6, in this case) are not shown.
For each property being compared, the top bar is annealed 70Ag-30Ni alloy and the bottom bar is annealed ASTM B522 class I.
