Annealed 70Ag-30Ni Alloy vs. Annealed ASTM B617

Both annealed 70Ag-30Ni alloy and annealed ASTM B617 are otherwise unclassified metals. Both are furnished in the annealed condition. They have 70% of their average alloy composition in common. There are 17 material properties with values for both materials. Properties with values for just one material (2, 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 B617.
