Solder Alloy 131 vs. 50Cr-50Ni-Cb Alloy

Both solder alloy 131 and 50Cr-50Ni-Cb alloy are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 17 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 solder alloy 131 and the bottom bar is 50Cr-50Ni-Cb alloy.
