Niobium Tube/Pipe Surface Finish
Depending on the intended applications, niobium tubes and pipes have three main surface finishes as follows:
- Negro: La superficie es "tal como se estampó" o "tal como se estiró", conservando una capa de lubricantes y óxidos de procesamiento.
- Limpio: La superficie se limpia químicamente para eliminar todos los lubricantes y óxidos.
- Suelo: The surface is centerless ground to remove all coating and to achieve precise dimensions control.
Niobium Tube/Pipe Applications
- Superconducting Technology: Niobium tubes and pipes can be used in superconducting magnets, such as in MRI machines and particle accelerators.
- Aeroespacial: Niobium tubes and pipes can be applied in engine components and rocket nozzles due to their high temperature and corrosion resistance.
