CC752S Brass vs. CR006A Copper

Both CC752S brass and CR006A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 63% of their average alloy composition in common. There are 26 material properties with values for both materials. Properties with values for just one material (3, in this case) are not shown.

For each property being compared, the top bar is CC752S brass and the bottom bar is CR006A copper.
