CC751S Brass vs. C85200 Brass

Both CC751S brass and C85200 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 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 CC751S brass and the bottom bar is C85200 brass.
