Nickel Beryllium 360 vs. R05200 Tantalum
Nickel beryllium 360 belongs to the nickel alloys classification, while R05200 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 nickel beryllium 360 and the bottom bar is R05200 tantalum.
