30 CF PEEK vs. 6061 Aluminum
30 CF PEEK and 6061 aluminum belong to fundamentally different material chemistries. 30 CF PEEK is a polymeric material, while 6061 aluminum is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 16 material properties with values for both materials. Properties with values for just one material (28, in this case) are not shown.
For each property being compared, the top bar is 30 CF PEEK and the bottom bar is 6061 aluminum.
