2024 Aluminum vs. Sandstone
2024 aluminum and sandstone belong to fundamentally different material chemistries. 2024 aluminum is a metal, while sandstone is a ceramic material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 15 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.
For each property being compared, the top bar is 2024 aluminum and the bottom bar is sandstone.
