Niobium Rod/Bar Production Process
- Materia prima: Seleccione alta pureza niobium powder.
- Pulvimetalurgia: Mezclar con aglutinante y compactar en un tocho verde.
- Sinterización: Sinterización a alta temperatura para eliminar el aglutinante y aumentar la densidad.
- Dibujo: Draw the rod to achieve the desired size and finish.
- Tratamiento térmico: Recocido para aliviar la tensión y mejorar las propiedades.
- Tratamiento de superficies: Limpiar y pulir la superficie.
- Corte y personalización: Cortar o personalizar según las necesidades.
Niobium Rod/Bar Processing Method
- Sinterización
- Forja
- Forja rotativa
- Rodando
- Pulido
Niobium Rod/Bar Surface Finish
Depending on the intended applications, niobium rods and bars 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 Rod/Bar Applications
- Aeroespacial: Engine parts and rocket nozzles
- Nuclear: Fuel cladding and control rods
- Superconducting: Superconducting magnets and MRI equipment
- Chemical: Corrosion-resistant equipment like reactors and pipes
- Electrónica: Capacitors and high-performance components
Niobium Rod/Bar Packaging
The Niobium Rod and Niobium Bar are 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.
