CC751S Brass vs. C37700 Brass

Both CC751S brass and C37700 brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 93% of their average alloy composition in common. There are 28 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is CC751S brass and the bottom bar is C37700 brass.
