C19020 Copper vs. AWS BVAg-18

C19020 copper belongs to the copper alloys classification, while AWS BVAg-18 belongs to the otherwise unclassified metals. They have a modest 31% 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 (10, in this case) are not shown.

For each property being compared, the top bar is C19020 copper and the bottom bar is AWS BVAg-18.
