C46200 Brass vs. Zamak 3

C46200 brass belongs to the copper alloys classification, while Zamak 3 belongs to the zinc alloys. They have a modest 36% of their average alloy composition in common, which, by itself, doesn't mean much. There are 27 material properties with values for both materials. Properties with values for just one material (9, in this case) are not shown.

For each property being compared, the top bar is C46200 brass and the bottom bar is Zamak 3.
