C87500 Brass vs. CC755S Brass

Both C87500 brass and CC755S brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 75% 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 C87500 brass and the bottom bar is CC755S brass.
