Zamak 3 vs. Titanium Diboride
Zamak 3 and titanium diboride belong to fundamentally different material chemistries. Zamak 3 is a metal, while titanium diboride is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 17 material properties with values for both materials. Properties with values for just one material (22, in this case) are not shown.
For each property being compared, the top bar is Zamak 3 and the bottom bar is titanium diboride.
