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