Niobium Tube Applications

Niobium pipe with one end closed

  • Niobium capillary tubes and tantalum capillary tubes are often used in high-pressure sodium lamp production.
  • Used as a structural material.
  • Used as a raw material for high-temperature alloys.
  • Used as a substrate for superconducting materials.
  • Used as a structural material for nuclear reactors.
  • Used as a material for medical devices.

Niobium Tube Packing

The Niobium Tubes will be carefully placed in wooden cases or cartons with additional support from soft materials to prevent any shifting during transportation. This packaging method guarantees the integrity of the products throughout the delivery process.
