Niobium Bar/rod

Niobium rod is a rod-shaped material made of niobium (chemical symbol Nb). Niobium is a transition metal belonging to the niobium-molybdenum family and has the following properties:
1. High melting point: The melting point of niobium is about 2468°C, which makes niobium rods have good stability in high temperature environments.
2. Corrosion resistance: Niobium has good corrosion resistance to most acids and alkalis, and is relatively stable even in aqua regia and hydrofluoric acid.
3. Low thermal expansion coefficient: Niobium has a low thermal expansion coefficient. Compared with other metals, the volume changes less when the temperature changes.
4. Good electrical conductivity and superconductivity: Niobium is a superconductor at low temperatures and can conduct current without loss.
5. Biocompatibility: Niobium has good compatibility with human tissues and can be used in the manufacture of medical devices.

Due to these properties, niobium rods are widely used in the following areas:
- Aerospace industry: used for high-temperature components, rocket nozzles, etc.
- Electronics industry: used as capacitors, resistors, inductors and other electronic component materials.
- Medical devices: such as pacemaker electrodes, orthopedic implants, etc.
- Chemical industry: for corrosion-resistant equipment and containers.
- Superconducting magnets: Superconducting magnet coils used in MRI (magnetic resonance imaging) equipment.

The manufacture of niobium rods typically involves a powder metallurgy or smelting process, followed by forging, rolling, etc., into the desired shape and size. Due to niobium's high melting point and special physical and chemical properties, its processing technology is relatively complex and requires precise temperature control and professional equipment.
