CC750S Brass vs. C86200 Bronze

Both CC750S brass and C86200 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 89% 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 CC750S brass and the bottom bar is C86200 bronze.
