Commercially Pure Silver vs. ASTM B563 Pd-Ag-Cu
Both commercially pure silver and ASTM B563 Pd-Ag-Cu are otherwise unclassified metals. They have a modest 38% 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 (3, in this case) are not shown.
For each property being compared, the top bar is commercially pure silver and the bottom bar is ASTM B563 Pd-Ag-Cu.
