AWS BVAg-32 vs. CR021A Copper

AWS BVAg-32 belongs to the otherwise unclassified metals classification, while CR021A copper belongs to the copper alloys. They have a modest 21% 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 (14, in this case) are not shown.

For each property being compared, the top bar is AWS BVAg-32 and the bottom bar is CR021A copper.
