3003 Aluminum vs. PGA
3003 aluminum and PGA belong to fundamentally different material chemistries. 3003 aluminum is a metal, while PGA 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 (24, in this case) are not shown.
For each property being compared, the top bar is 3003 aluminum and the bottom bar is PGA.
