2024 Aluminum vs. FKM Rubber

2024 aluminum and FKM rubber belong to fundamentally different material chemistries. 2024 aluminum is a metal, while FKM rubber is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 6 material properties with values for both materials. Properties with values for just one material (27, in this case) are not shown.

For each property being compared, the top bar is 2024 aluminum and the bottom bar is FKM rubber.
