Commercially Pure Zirconium vs. Reactor Grade Zirconium
Both commercially pure zirconium and reactor grade zirconium are otherwise unclassified metals. Both are furnished in the annealed condition. They have a very high 97% of their average alloy composition in common. There are 20 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.
For each property being compared, the top bar is commercially pure zirconium and the bottom bar is reactor grade zirconium.
