AWS BAu-1 vs. ASTM B628 Ag-Cu

Both AWS BAu-1 and ASTM B628 Ag-Cu are otherwise unclassified metals. 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 (5, in this case) are not shown.

For each property being compared, the top bar is AWS BAu-1 and the bottom bar is ASTM B628 Ag-Cu.
