Commercially Pure Silver vs. Type 2 Niobium

Both commercially pure silver and Type 2 niobium are otherwise unclassified metals. There are 16 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 Type 2 niobium.
