CC760S Brass vs. AWS BAg-21

CC760S brass belongs to the copper alloys classification, while AWS BAg-21 belongs to the otherwise unclassified metals. They have a modest 29% of their average alloy composition in common, which, by itself, doesn't mean much. There are 16 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 CC760S brass and the bottom bar is AWS BAg-21.
