Commercially Pure Zinc vs. ACI-ASTM CA40F Steel

Commercially pure zinc belongs to the zinc alloys classification, while ACI-ASTM CA40F steel belongs to the iron alloys. There are 28 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 ACI-ASTM CA40F steel.
