Solder Alloy 142 vs. Grade 7 Babbitt Metal

Both solder alloy 142 and grade 7 Babbitt Metal are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 59% of their average alloy composition in common. There are 14 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.

For each property being compared, the top bar is solder alloy 142 and the bottom bar is grade 7 Babbitt Metal.
