R05400 Tantalum vs. R60901 Alloy

Both R05400 tantalum and R60901 alloy are otherwise unclassified metals. 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 R60901 alloy.
