ASTM A148 Cast Steel vs. Commercially Pure Zirconium
ASTM A148 cast steel belongs to the iron alloys classification, while commercially pure zirconium belongs to the otherwise unclassified metals. There are 21 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 ASTM A148 cast steel and the bottom bar is commercially pure zirconium.
