PA 4/6 vs. R30075 Cobalt
PA 4/6 and R30075 cobalt belong to fundamentally different material chemistries. PA 4/6 is a polymeric material, while R30075 cobalt 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 (30, in this case) are not shown.
For each property being compared, the top bar is PA 4/6 and the bottom bar is R30075 cobalt.
