CC752S Brass vs. C87900 Brass

Both CC752S brass and C87900 brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 97% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is CC752S brass and the bottom bar is C87900 brass.
