PVC-P vs. 4145 Aluminum
PVC-P and 4145 aluminum belong to fundamentally different material chemistries. PVC-P is a polymeric material, while 4145 aluminum is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 16 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 PVC-P and the bottom bar is 4145 aluminum.
