AWS BAg-37 vs. Commercially Pure Silver

Both AWS BAg-37 and commercially pure silver are otherwise unclassified metals. They have a modest 25% of their average alloy composition in common, which, by itself, doesn't mean much. There are 15 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is AWS BAg-37 and the bottom bar is commercially pure silver.
