AWS BAg-7 vs. CC140C Copper
AWS BAg-7 belongs to the otherwise unclassified metals classification, while CC140C copper belongs to the copper alloys. They have a modest 22% 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-7 and the bottom bar is CC140C copper.
