C36200 Brass vs. ASTM B780 Alloy

C36200 brass belongs to the copper alloys classification, while ASTM B780 alloy belongs to the otherwise unclassified metals. They have a modest 25% 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 C36200 brass and the bottom bar is ASTM B780 alloy.
