ASTM B628 Ag-Cu vs. Austenitic Nodular Cast Iron

ASTM B628 Ag-Cu belongs to the otherwise unclassified metals classification, while austenitic nodular cast iron belongs to the iron alloys. There are 16 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is ASTM B628 Ag-Cu and the bottom bar is austenitic nodular cast iron.
