Class 4 Tungsten vs. Grade 15 Babbitt Metal

Both class 4 tungsten and grade 15 Babbitt Metal are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 12 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.

For each property being compared, the top bar is class 4 tungsten and the bottom bar is grade 15 Babbitt Metal.
