2024 Aluminum vs. DAP
2024 aluminum and DAP belong to fundamentally different material chemistries. 2024 aluminum is a metal, while DAP is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 13 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 2024 aluminum and the bottom bar is DAP.
