Commercially Pure Silver vs. Grade CY40 Nickel

Commercially pure silver belongs to the otherwise unclassified metals classification, while grade CY40 nickel belongs to the nickel alloys. There are 20 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is commercially pure silver and the bottom bar is grade CY40 nickel.
