C91000 Bronze vs. C92700 Bronze

Both C91000 bronze and C92700 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 97% of their average alloy composition in common. There are 28 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 C91000 bronze and the bottom bar is C92700 bronze.
