3003 Aluminum vs. Thermoplastic PI
3003 aluminum and thermoplastic PI belong to fundamentally different material chemistries. 3003 aluminum is a metal, while thermoplastic PI is a polymeric material. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 9 material properties with values for both materials. Properties with values for just one material (29, in this case) are not shown.
For each property being compared, the top bar is 3003 aluminum and the bottom bar is thermoplastic PI.
