R05255 Alloy vs. Z20301 Zinc

R05255 alloy belongs to the otherwise unclassified metals classification, while Z20301 zinc belongs to the zinc alloys. There are 20 material properties with values for both materials. Properties with values for just one material (8, 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 R05255 alloy and the bottom bar is Z20301 zinc.
