50Cr-50Ni Alloy vs. Solder Alloy 181

Both 50Cr-50Ni alloy and solder alloy 181 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 16 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is 50Cr-50Ni alloy and the bottom bar is solder alloy 181.
