Commercially Pure Silver vs. ASTM B617 Coin Silver
Both commercially pure silver and ASTM B617 coin silver are otherwise unclassified metals. They have a moderately high 90% of their average alloy composition in common. There are 19 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 commercially pure silver and the bottom bar is ASTM B617 coin silver.
