30 GF PEI vs. 6061 Aluminum
30 GF PEI and 6061 aluminum belong to fundamentally different material chemistries. 30 GF PEI 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 14 material properties with values for both materials. Properties with values for just one material (32, in this case) are not shown.
For each property being compared, the top bar is 30 GF PEI and the bottom bar is 6061 aluminum.
