Cesium Bromide vs. SAE-AISI 4150 Steel
Cesium bromide and SAE-AISI 4150 steel belong to fundamentally different material chemistries. Cesium bromide is a ceramic material, while SAE-AISI 4150 steel 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 (23, in this case) are not shown.
For each property being compared, the top bar is cesium bromide and the bottom bar is SAE-AISI 4150 steel.
