Niobium Tube, Niobium Pipe
Niobium tubes or pipes are made of pure niobium metal or niobium alloys and are used in various high-temperature applications such as superconducting magnets, nuclear reactors, and aerospace industries. Niobium tubes and pipes have excellent corrosion resistance, high melting point, and good ductility. They can withstand high temperatures and extreme environments without losing their mechanical and chemical properties. Niobium tubes are used as critical components in chemical processing equipment, heat exchangers, and medical implants. They are also used in electrical and electronic applications such as capacitors, vacuum tubes, and semiconductors. Niobium tubes and pipes are available in various sizes, thicknesses, and lengths, and can be customized according to specific requirements.
