Grade 8 Babbitt Metal vs. Grade 7 Babbitt Metal
Both grade 8 Babbitt Metal and grade 7 Babbitt Metal are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 95% of their average alloy composition in common. There are 19 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.
For each property being compared, the top bar is grade 8 Babbitt Metal and the bottom bar is grade 7 Babbitt Metal.
