C84800 Brass vs. CC490K Brass

Both C84800 brass and CC490K 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 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 C84800 brass and the bottom bar is CC490K brass.
