Yttria vs. Zamak 3
Yttria and Zamak 3 belong to fundamentally different material chemistries. Yttria 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 11 material properties with values for both materials. Properties with values for just one material (26, in this case) are not shown.
For each property being compared, the top bar is yttria and the bottom bar is Zamak 3.
