C35600 Brass vs. Zamak 5

C35600 brass belongs to the copper alloys classification, while Zamak 5 belongs to the zinc alloys. They have a modest 37% of their average alloy composition in common, which, by itself, doesn't mean much. There are 25 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.

For each property being compared, the top bar is C35600 brass and the bottom bar is Zamak 5.
