Grade 705C Zirconium vs. 60Cr-40Ni Alloy

Both grade 705C zirconium and 60Cr-40Ni alloy are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 16 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is grade 705C zirconium and the bottom bar is 60Cr-40Ni alloy.
