Grade 2 Babbitt Metal vs. Solder Alloy 191

Both grade 2 Babbitt Metal and solder alloy 191 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 13 material properties with values for both materials. Properties with values for just one material (15, in this case) are not shown.

For each property being compared, the top bar is grade 2 Babbitt Metal and the bottom bar is solder alloy 191.
