CC755S Brass vs. C84200 Brass

Both CC755S brass and C84200 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 CC755S brass and the bottom bar is C84200 brass.
