Annealed ASTM B780 Alloy vs. Annealed Silver
Both annealed ASTM B780 alloy and annealed silver are otherwise unclassified metals. Both are furnished in the annealed condition. They have 75% of their average alloy composition in common. There are 18 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 annealed ASTM B780 alloy and the bottom bar is annealed silver.
