CC763S Brass vs. C85400 Brass

Both CC763S brass and C85400 brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 92% of their average alloy composition in common. There are 27 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 CC763S brass and the bottom bar is C85400 brass.
