ASTM B628 Ag-Cu vs. Type 2 Pewter
Both ASTM B628 Ag-Cu and Type 2 pewter are otherwise unclassified metals. There are 15 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.
For each property being compared, the top bar is ASTM B628 Ag-Cu and the bottom bar is Type 2 pewter.
