PVC-P vs. 7049A Aluminum

PVC-P and 7049A aluminum belong to fundamentally different material chemistries. PVC-P is a polymeric material, while 7049A 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 (25, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is PVC-P and the bottom bar is 7049A aluminum.
