Cold Worked R05200 Tantalum vs. Hard Drawn ASTM B596
Both cold worked R05200 tantalum and hard drawn ASTM B596 are otherwise unclassified metals. Both are furnished in the cold worked (strain hardened) condition. There are 15 material properties with values for both materials. Properties with values for just one material (10, in this case) are not shown.
For each property being compared, the top bar is cold worked R05200 tantalum and the bottom bar is hard drawn ASTM B596.
