AWS BVAu-2 vs. C82600 Copper

AWS BVAu-2 belongs to the otherwise unclassified metals classification, while C82600 copper 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 (13, in this case) are not shown.

For each property being compared, the top bar is AWS BVAu-2 and the bottom bar is C82600 copper.
