Tantalum  Ingot Applications

Tantalum Ingot is mainly used to manufacture various tantalum and tantalum alloy materials, widely applied in the following areas:

  • Aerospace
  • Chemical industry
  • Medical industry
  • Electronics
  • Nuclear industry
  • Metallurgy

Tantalum and Tantalum Alloy

  • 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, vacuum-arc melt, or both.
  • R05240, tantalum alloy, 60 % tantalum, 40 % niobium, electron-beam furnace or vacuum-arc melt.

Tantalum Ingot Packaging

The Tantalum Ingot 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.
