Commercially Pure Zinc vs. ASTM Grade HN Steel

Commercially pure zinc belongs to the zinc alloys classification, while ASTM grade HN steel belongs to the iron alloys. There are 23 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is commercially pure zinc and the bottom bar is ASTM grade HN steel.
