CC753S Brass vs. CR012A Copper

Both CC753S brass and CR012A copper are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 59% 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 CC753S brass and the bottom bar is CR012A copper.
