CC761S Brass vs. CR016A Copper

Both CC761S brass and CR016A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 81% 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 CC761S brass and the bottom bar is CR016A copper.
