C84200 Brass vs. C93200 Bronze

Both C84200 brass and C93200 bronze are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 92% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (4, in this case) are not shown.

For each property being compared, the top bar is C84200 brass and the bottom bar is C93200 bronze.
