Solder Alloy 301 vs. Grade 1 Babbitt Metal
Both solder alloy 301 and grade 1 Babbitt Metal are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 42% of their average alloy composition in common. There are 21 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 301 and the bottom bar is grade 1 Babbitt Metal.
