Cork vs. R30001 Cobalt

Cork and R30001 cobalt belong to fundamentally different material chemistries. Cork is a polymeric material, while R30001 cobalt is a metal. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 15 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown. Please note that the two materials have significantly dissimilar densities. This means that additional care is required when interpreting the data, because some material properties are based on units of mass, while others are based on units of area or volume.

For each property being compared, the top bar is cork and the bottom bar is R30001 cobalt.
