50Cr-50Ni Alloy vs. Grade 7 Babbitt Metal

Both 50Cr-50Ni alloy and grade 7 Babbitt Metal are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 15 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.

For each property being compared, the top bar is 50Cr-50Ni alloy and the bottom bar is grade 7 Babbitt Metal.
