Grade 7 Babbitt Metal vs. Solder Alloy 137
Both grade 7 Babbitt Metal and solder alloy 137 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 86% of their average alloy composition in common. There are 15 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.
For each property being compared, the top bar is grade 7 Babbitt Metal and the bottom bar is solder alloy 137.
