6061 Aluminum vs. PES
6061 aluminum and PES belong to fundamentally different material chemistries. 6061 aluminum is a metal, while PES is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 14 material properties with values for both materials. Properties with values for just one material (34, in this case) are not shown.
For each property being compared, the top bar is 6061 aluminum and the bottom bar is PES.
