C67600 Bronze vs. ASTM B628 Ag-Cu

C67600 bronze belongs to the copper alloys classification, while ASTM B628 Ag-Cu belongs to the otherwise unclassified metals. They have a modest 28% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is C67600 bronze and the bottom bar is ASTM B628 Ag-Cu.
