ACI-ASTM CB30 Steel vs. Commercially Pure Zirconium

ACI-ASTM CB30 steel belongs to the iron alloys classification, while commercially pure zirconium belongs to the otherwise unclassified metals. There are 18 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

For each property being compared, the top bar is ACI-ASTM CB30 steel and the bottom bar is commercially pure zirconium.
