Grade 704C Zirconium vs. Low-oxygen Zirconium

Both grade 704C zirconium and low-oxygen 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 (2, in this case) are not shown.

For each property being compared, the top bar is grade 704C zirconium and the bottom bar is low-oxygen zirconium.
