C15900 Copper vs. AWS BVAu-2

C15900 copper belongs to the copper alloys classification, while AWS BVAu-2 belongs to the otherwise unclassified metals. 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 (16, in this case) are not shown.

For each property being compared, the top bar is C15900 copper and the bottom bar is AWS BVAu-2.
