Grade 3 Babbitt Metal vs. AWS BAu-2
Both grade 3 Babbitt Metal and AWS BAu-2 are otherwise unclassified metals. Both are furnished in the as-fabricated (no temper or treatment) condition. There are 11 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.
For each property being compared, the top bar is grade 3 Babbitt Metal and the bottom bar is AWS BAu-2.
