Commercially Pure Zinc vs. ASTM B628 Ag-Cu

Commercially pure zinc belongs to the zinc alloys classification, while ASTM B628 Ag-Cu belongs to the otherwise unclassified metals. There are 18 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 commercially pure zinc and the bottom bar is ASTM B628 Ag-Cu.
