Full-hard 85-silver 15-nickel vs. Full-hard ASTM B780 Alloy
Both full-hard 85-silver 15-nickel and full-hard ASTM B780 alloy are otherwise unclassified metals. Both are furnished in the full-hard temper. They have 76% of their average alloy composition in common. There are 16 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is full-hard 85-silver 15-nickel and the bottom bar is full-hard ASTM B780 alloy.
