C86800 Bronze vs. CC764S Brass

Both C86800 bronze and CC764S brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 96% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is C86800 bronze and the bottom bar is CC764S brass.
