AWS BAg-2 vs. CC490K Brass

AWS BAg-2 belongs to the otherwise unclassified metals classification, while CC490K brass belongs to the copper alloys. They have a modest 34% 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 (13, in this case) are not shown.

For each property being compared, the top bar is AWS BAg-2 and the bottom bar is CC490K brass.
