6061 Aluminum vs. ECO Rubber
6061 aluminum and ECO rubber belong to fundamentally different material chemistries. 6061 aluminum is a metal, while ECO rubber is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 12 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.
For each property being compared, the top bar is 6061 aluminum and the bottom bar is ECO rubber.
