Niobium Plate/Sheet/Disc Surface Finish

Depending on the intended applications, niobium plate, sheet, and disc 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.

Niobium Plate/Sheet/Disc Applications

• Superconducting Materials: Niobium plates, sheets, and discs are widely used in the field of superconductivity and are commonly used to produce superconducting cables, superconducting magnets, and other devices, especially in particle gas pedals and nuclear magnetic resonance (NMR) instruments.
• Industria nuclear: Niobium plates, sheets, and discs are commonly used as structural materials in nuclear reactors and nuclear fuel jacket materials due to their low neutron capture cross section and high corrosion resistance.
• Aeroespacial: Due to their excellent high-temperature strength and heat resistance, Niobium plates, sheets, and discs are often used to manufacture high-temperature components, such as engine components for rockets and airplanes.
• Electronic Components: Niobium plates, sheets, and discs are used as acid and liquid metal corrosion-resistant materials in manufacturing boilers, heaters, and other equipment.
• Industria química: Niobium plates, sheets, and discs are used as acid and liquid metal corrosion-resistant materials for boilers, heaters, and other equipment.

Niobium Plate/Sheet/Disc Packaging

The Niobium Plate/Sheet/Disc is 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.
