2124 Aluminum vs. Grade 3 Babbitt Metal

2124 aluminum belongs to the aluminum alloys classification, while grade 3 Babbitt Metal belongs to the otherwise unclassified metals. There are 17 material properties with values for both materials. Properties with values for just one material (15, 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 2124 aluminum and the bottom bar is grade 3 Babbitt Metal.
