Alumina vs. PA 6/6
Alumina and PA 6/6 belong to fundamentally different material chemistries. Alumina is a ceramic material, while PA 6/6 is polymeric. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 8 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 alumina and the bottom bar is PA 6/6.
