CC755S Brass vs. CR003A Copper

Both CC755S brass and CR003A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 60% 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 CC755S brass and the bottom bar is CR003A copper.
