50Cr-50Ni-Cb Alloy vs. Class 3 Tungsten

Both 50Cr-50Ni-Cb alloy and class 3 tungsten are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 20 material properties with values for both materials. Properties with values for just one material (6, in this case) are not shown.

For each property being compared, the top bar is 50Cr-50Ni-Cb alloy and the bottom bar is class 3 tungsten.
