AWS BAg-10 vs. C72500 Copper-nickel

AWS BAg-10 belongs to the otherwise unclassified metals classification, while C72500 copper-nickel belongs to the copper alloys. They have a modest 20% 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 (12, in this case) are not shown.

For each property being compared, the top bar is AWS BAg-10 and the bottom bar is C72500 copper-nickel.
