Z40101 Zinc vs. Zamak 2

Both Z40101 zinc and Zamak 2 are zinc 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 (7, in this case) are not shown.

For each property being compared, the top bar is Z40101 zinc and the bottom bar is Zamak 2.
