C85900 Brass vs. C86500 Bronze

Both C85900 brass and C86500 bronze 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 28 material properties with values for both materials. Properties with values for just one material (1, in this case) are not shown.

For each property being compared, the top bar is C85900 brass and the bottom bar is C86500 bronze.
