As-cast C95500 Bronze vs. As-cast C99750 Brass

Both as-cast C95500 bronze and as-cast C99750 brass are copper alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 65% of their average alloy composition in common. There are 27 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 as-cast C95500 bronze and the bottom bar is as-cast C99750 brass.
