3003 Aluminum vs. Thermoset PI
3003 aluminum and thermoset PI belong to fundamentally different material chemistries. 3003 aluminum is a metal, while thermoset PI is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 10 material properties with values for both materials. Properties with values for just one material (36, in this case) are not shown.
For each property being compared, the top bar is 3003 aluminum and the bottom bar is thermoset PI.
