Aluminum Nitride vs. Grade 5 Titanium

Aluminum nitride and grade 5 titanium belong to fundamentally different material chemistries. Aluminum nitride is a ceramic material, while grade 5 titanium is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 10 material properties with values for both materials. Properties with values for just one material (32, in this case) are not shown.

For each property being compared, the top bar is aluminum nitride and the bottom bar is grade 5 titanium.
