Commercially Pure Zinc vs. ASTM B631 Class C

Commercially pure zinc belongs to the zinc alloys classification, while ASTM B631 class C belongs to the otherwise unclassified metals. There are 16 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.

For each property being compared, the top bar is commercially pure zinc and the bottom bar is ASTM B631 class C.
