Grade 8 Babbitt Metal vs. Solder Alloy 704

Both grade 8 Babbitt Metal and solder alloy 704 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. 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 grade 8 Babbitt Metal and the bottom bar is solder alloy 704.
