Solder Alloy 301 vs. 50Cr-50Ni Alloy

Both solder alloy 301 and 50Cr-50Ni alloy are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 19 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 solder alloy 301 and the bottom bar is 50Cr-50Ni alloy.
