Magnesium titanate and Zamak 3 belong to fundamentally different material chemistries. Magnesium titanate 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 5 material properties with values for both materials. Properties with values for just one material (37, in this case) are not shown.
For each property being compared, the top bar is magnesium titanate and the bottom bar is Zamak 3.
