Cesium Iodide vs. Grade 5 Titanium
Cesium iodide and grade 5 titanium belong to fundamentally different material chemistries. Cesium iodide 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 11 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 cesium iodide and the bottom bar is grade 5 titanium.
