ASTM B628 Ag-Cu vs. C23400 Brass
ASTM B628 Ag-Cu belongs to the otherwise unclassified metals classification, while C23400 brass belongs to the copper alloys. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 15 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 ASTM B628 Ag-Cu and the bottom bar is C23400 brass.
