Commercially Pure Zinc vs. Austempered Cast Iron

Commercially pure zinc belongs to the zinc alloys classification, while austempered cast iron belongs to the iron alloys. There are 25 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is commercially pure zinc and the bottom bar is austempered cast iron.
