Solder Alloy 171 vs. Grade 15 Babbitt Metal
Both solder alloy 171 and grade 15 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 14 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 solder alloy 171 and the bottom bar is grade 15 Babbitt Metal.
