6061 aluminum and CR rubber belong to fundamentally different material chemistries. 6061 aluminum is a metal, while CR rubber is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 9 material properties with values for both materials. Properties with values for just one material (26, in this case) are not shown.
For each property being compared, the top bar is 6061 aluminum and the bottom bar is CR rubber.
