C84000 Brass vs. C83400 Brass

Both C84000 brass and C83400 brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a very high 96% of their average alloy composition in common. There are 28 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 C84000 brass and the bottom bar is C83400 brass.
