Solder Alloy 123 vs. 50Cr-50Ni-Cb Alloy
Both solder alloy 123 and 50Cr-50Ni-Cb alloy 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 (10, in this case) are not shown.
For each property being compared, the top bar is solder alloy 123 and the bottom bar is 50Cr-50Ni-Cb alloy.
