4045 Aluminum vs. LCP
4045 aluminum and LCP belong to fundamentally different material chemistries. 4045 aluminum is a metal, while LCP 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 (26, in this case) are not shown.
For each property being compared, the top bar is 4045 aluminum and the bottom bar is LCP.
