CR011A Copper vs. CC752S Brass

Both CR011A copper and CC752S brass 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 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 CR011A copper and the bottom bar is CC752S brass.
