C91100 Bronze vs. C91300 Bell Metal

Both C91100 bronze and C91300 bell metal are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 98% of their average alloy composition in common. There are 27 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is C91100 bronze and the bottom bar is C91300 bell metal.
