7075 Aluminum vs. UF
7075 aluminum and UF belong to fundamentally different material chemistries. 7075 aluminum is a metal, while UF 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 (20, in this case) are not shown.
For each property being compared, the top bar is 7075 aluminum and the bottom bar is UF.
