50Cr-50Ni-Cb Alloy vs. Grade 702C Zirconium

Both 50Cr-50Ni-Cb alloy and grade 702C zirconium are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 18 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.

For each property being compared, the top bar is 50Cr-50Ni-Cb alloy and the bottom bar is grade 702C zirconium.
