Solder Alloy 136 vs. Grade 1 Babbitt Metal

Both solder alloy 136 and grade 1 Babbitt Metal are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a modest 27% of their average alloy composition in common, which, by itself, doesn't mean much. There are 20 material properties with values for both materials. Properties with values for just one material (8, in this case) are not shown.

For each property being compared, the top bar is solder alloy 136 and the bottom bar is grade 1 Babbitt Metal.
