Commercially Pure Zinc vs. Grade 250 Maraging Steel

Commercially pure zinc belongs to the zinc alloys classification, while grade 250 maraging steel belongs to the iron alloys. There are 22 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is commercially pure zinc and the bottom bar is grade 250 maraging steel.
