C91300 Bell Metal vs. Type 2 Pewter

C91300 bell metal belongs to the copper alloys classification, while Type 2 pewter belongs to the otherwise unclassified metals. They have a modest 21% of their average alloy composition in common, which, by itself, doesn't mean much. There are 19 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is C91300 bell metal and the bottom bar is Type 2 pewter.
