PA 4/6 and ACI-ASTM CD4MCu steel belong to fundamentally different material chemistries. PA 4/6 is a polymeric material, while ACI-ASTM CD4MCu steel is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 4 material properties with values for both materials. Properties with values for just one material (33, in this case) are not shown.
For each property being compared, the top bar is PA 4/6 and the bottom bar is ACI-ASTM CD4MCu steel.
