Commercially Pure Zirconium vs. Grade 704C Zirconium
Both commercially pure zirconium and grade 704C zirconium are otherwise unclassified metals. They have a very high 98% of their average alloy composition in common. There are 20 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.
For each property being compared, the top bar is commercially pure zirconium and the bottom bar is grade 704C zirconium.
