6061 aluminum and zinc sulfide belong to fundamentally different material chemistries. 6061 aluminum 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 6061 aluminum and the bottom bar is zinc sulfide.
