Standard Specification for Tantalum and Tantalum Alloy Rod and Wire
The following bibliographic material is provided to assist you with your purchasing decision:
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.
Scope
1.1 This specification covers unalloyed and alloyed tantalum rod and wire.
1.2 The materials covered by this specification are:
1.2.1 R05200, unalloyed tantalum, electron-beam furnace or vacuum-arc melt, or both,
1.2.2 R05400, unalloyed tantalum, powder-metallurgy consolidation,
1.2.3 R05255, tantalum alloy, 90 % tantalum 10 % tungsten, electron-beam furnace or vacuum-arc melt, or both,
1.2.4 R05252, tantalum alloy, 97.5 % tantalum 2.5 % tungsten, electron-beam furnace or vacuum-arc melt, or both, and
1.2.5 R05240 tantalum alloy, 60 % tantalum 40 % columbium, electron-beam furnace or vacuum-arc melt, or both.
1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only.
