Solder Alloy 121 vs. Grade 2 Babbitt Metal

Both solder alloy 121 and grade 2 Babbitt Metal 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 (12, in this case) are not shown.

For each property being compared, the top bar is solder alloy 121 and the bottom bar is grade 2 Babbitt Metal.
