Austenitic Nodular Cast Iron vs. R05400 Tantalum
Austenitic nodular cast iron belongs to the iron alloys classification, while R05400 tantalum belongs to the otherwise unclassified metals. There are 18 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 austenitic nodular cast iron and the bottom bar is R05400 tantalum.
