CC750S Brass vs. C68000 Brass

Both CC750S brass and C68000 brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 91% of their average alloy composition in common. There are 26 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 CC750S brass and the bottom bar is C68000 brass.
