Tantalum and Tantalum Alloys

  • R05200, unalloyed tantalum, electron-beam furnace vacuum-arc melt, or both
  • R05400, unalloyed tantalum, powder-metallurgy consolidation.
  • R05255, tantalum alloy, 90 % tantalum, 10 % tungsten, electron-beam furnace of vacuum-arc melt, or both.
  • R05252, tantalum alloy, 97.5 % tantalum, 2.5 % tungsten, electron-beam furnace or vacuum-arc melt, or both.
  • R05240, tantalum alloy, 60 % tantalum, 40 % niobium, electron-beam furnace or vacuum-arc melt.

Tantalum Wire Packaging

The Tantalum Wire is carefully placed in wooden cases or cartons, with additional support from soft materials, to prevent shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
