Remarks

6061 aluminum and PEEK belong to fundamentally different material chemistries. 6061 aluminum is a metal, while PEEK is a polymeric material. 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 (15 in this case) are not shown.
