Cold Worked R05200 Tantalum vs. Cold Worked R60901 Alloy
Both cold worked R05200 tantalum and cold worked R60901 alloy are otherwise unclassified metals. Both are furnished in the cold worked (strain hardened) condition. 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 cold worked R05200 tantalum and the bottom bar is cold worked R60901 alloy.
