Annealed ASTM B628 vs. Annealed R05200 Tantalum
Both annealed ASTM B628 and annealed R05200 tantalum are otherwise unclassified metals. Both are furnished in the annealed 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 annealed ASTM B628 and the bottom bar is annealed R05200 tantalum.
