AWS BAg-2a vs. CR009A Copper

AWS BAg-2a belongs to the otherwise unclassified metals classification, while CR009A copper belongs to the copper alloys. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 17 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-2a and the bottom bar is CR009A copper.
