ASTM B563 Pd-Ag-Cu vs. Commercially Pure Zinc

ASTM B563 Pd-Ag-Cu belongs to the otherwise unclassified metals classification, while commercially pure zinc belongs to the zinc alloys. There are 18 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.

For each property being compared, the top bar is ASTM B563 Pd-Ag-Cu and the bottom bar is commercially pure zinc.
