C15500 Copper vs. AWS BAg-27

C15500 copper belongs to the copper alloys classification, while AWS BAg-27 belongs to the otherwise unclassified metals. They have a modest 35% 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 (14, in this case) are not shown.

For each property being compared, the top bar is C15500 copper and the bottom bar is AWS BAg-27.
