CR003A Copper vs. C83300 Brass

Both CR003A copper and C83300 brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have a moderately high 93% 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 CR003A copper and the bottom bar is C83300 brass.
