R60704 Alloy vs. R05400 Tantalum

Both R60704 alloy and R05400 tantalum 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 R60704 alloy and the bottom bar is R05400 tantalum.
