CC750S Brass vs. CR009A Copper

Both CC750S brass and CR009A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 65% 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 CC750S brass and the bottom bar is CR009A copper.
