R05400 Tantalum vs. C34200 Brass
R05400 tantalum belongs to the otherwise unclassified metals classification, while C34200 brass belongs to the copper alloys. There are 20 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 R05400 tantalum and the bottom bar is C34200 brass.
