This specification covers unalloyed and alloyed tantalum rod and wire. The materials covered are: R05200, R05400, R05255, R05252, and R05240. These materials shall be made from vacuum-arc melted or electron-beam melted ingots or powder-metallurgy consolidated unalloyed tantalum. The chemical composition shall conform to the required contents of carbon, oxygen, nitrogen, hydrogen, niobium, iron, titanium, tungsten, molybdenum, silicon, nickel, and tantalum. Chemical analysis shall be made. Mechanical properties shall conform to the required tensile strength, yield strength, and elongation.

This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
