CC497K Bronze vs. Grade 7 Babbitt Metal

CC497K bronze belongs to the copper alloys classification, while grade 7 Babbitt Metal belongs to the otherwise unclassified metals. They have a modest 26% of their average alloy composition in common, which, by itself, doesn't mean much. There are 18 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 CC497K bronze and the bottom bar is grade 7 Babbitt Metal.
