R60901 Alloy vs. Commercially Pure Zirconium

Both R60901 alloy and commercially pure zirconium are otherwise unclassified metals. 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 R60901 alloy and the bottom bar is commercially pure zirconium.
