C84200 Brass vs. CC140C Copper

Both C84200 brass and CC140C copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 80% 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 C84200 brass and the bottom bar is CC140C copper.
