Ferrite vs. Zamak 3
Ferrite and Zamak 3 belong to fundamentally different material chemistries. Ferrite is a ceramic material, while Zamak 3 is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 15 material properties with values for both materials. Properties with values for just one material (24, in this case) are not shown.
For each property being compared, the top bar is ferrite and the bottom bar is Zamak 3.
