Solder Alloy 151 vs. Grade 8 Babbitt Metal
Both solder alloy 151 and grade 8 Babbitt Metal are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. 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 151 and the bottom bar is grade 8 Babbitt Metal.
